Unclaimed page — not yet verified by VerifiedHer. Is this you?
Real, and documented primarily through a reality-TV screen credit and named press coverage of a charity fundraiser, rather than through influencer self-promotion alone. Lavaxgrll — Instagram handle @lavaxgrll, whose own account displays the name "Mariah Casillas" in Instagram's own page metadata — is a cast contestant credited as "Self" across all 10 episodes of the third season of The Reality House, a YouTube reality competition series produced by creators Kian Lawley and JC Caylen; TMDB's own independently loaded cast listing confirms the "Self - Contestant," 10-episode credit, and IMDb's own structured credit data (independently indexed by search engines, though IMDb's page itself returned an access-blocked response to this research's automated fetch) attributes that same credit specifically to "Mariah Casillas." Season 3 premiered November 19, 2021 and concluded January 22, 2022, airing alongside cast members including Tana Mongeau, Bryce Hall, and Peter Vigilante. Separately, IMDb also credits her — again via search-indexed data, since IMDb's own page blocked direct automated fetch — with a role as "Diner Customer" in "42 Seconds" (2024), an independent short drama film shot in Superior, Arizona, written by Judith Eisenberg and directed by Steve Anderson, about survivors of a diner shooting returning to the scene. In August 2023, TMZ (staff-reported, Aug. 21–22, 2023) covered her under the name Mariah Casillas after she launched a GoFundMe campaign offering a nude photo for every $10 donated to Maui wildfire relief; GoFundMe removed the campaign and refunded roughly $7,800 in donations for a terms-of-service violation, and she continued the fundraiser through her own OnlyFans account, ultimately raising more than $10,000 for wildfire relief — she also appeared on TMZ Live the same week to discuss it, a verified real-time media appearance documented by TMZ's own reporting. Earlier that year, Naluda Magazine published an interview with her (July 25, 2023, under the LavaGrll name) in which she discussed starting her online career during the pandemic, saying: "I firmly believed I could repay the money by being innovative and creative online" — she also told the magazine her nickname originated from fans calling her "lava girl" during an earlier pink-haired phase online. Multiple lower-quality aggregator and bio-farm sites additionally describe her as the outright winner of The Reality House's third season; this research found no independently confirmable named-press or platform-official source specifically confirming winner status beyond the documented 10-episode cast credit above, so that specific claim is treated as reported rather than documented. No official AI-persona statement, platform AI label, or operator claim of a virtual model was found anywhere in this research. This page is unclaimed and compiled from public sources.
All of her, everywhere — every known account
- Instagram @lavaxgrll Appears official Primary account; Instagram's own page metadata displays the name "Mariah Casillas," matching the identity documented via TMZ and IMDb/TMDB press coverage. Widely reported at roughly 440K followers; account activity reconfirmed via a March 2026 indexed post. Instagram's login wall prevented independent confirmation of the current bio text or exact follower count via automated fetch.
- OnlyFans — Unverified TMZ (Aug. 21, 2023) documented that she raised funds via her own OnlyFans account during a Maui-wildfire charity fundraiser. This research found no more recent named-press or first-party confirmation that the account remains active. No account address is reproduced here regardless — reach any legitimate paid account only through her own currently posted official links, never a search-result "leak" page.
Quick answers
What is Lavaxgrll's real name?
Instagram's own page metadata for her account (@lavaxgrll) displays the name "Mariah Casillas" — a self-configured display-name field, not a press guess or aggregator invention. Instagram's login wall prevented this research from browsing the live account directly to reconfirm the field in real time, but it is captured consistently across multiple independently indexed page snapshots, including one from a March 30, 2026 post still titled "Photos by Mariah Casillas (@lavaxgrll)" — recent, ongoing use, not a one-time artifact. The same name is independently corroborated by TMZ's named coverage of her and by IMDb/TMDB's screen credits tied to the same handle-linked identity. This is not a doxx — it's the name she configures on her own account, the same self-disclosure standard applied elsewhere on this site to a creator's own account display-name field (e.g., CandyLion's Instagram/TikTok display name).
Is every “Lavaxgrll” online the same person?
No — the name gets tangled with others, and telling them apart is half the point of this page.
- Multiple Instagram accounts use close variations of her handle (including @lavagrllx, @lavaxxgrl, @lavaagrl, and @lavaaxgrl) and surface in searches for her name; none is confirmed as an account she personally operates via any first-party hub this research could access — only @lavaxgrll, matching the identity documented via TMZ and IMDb/TMDB press coverage as Mariah Casillas, is treated as hers.
- A cluster of similarly spelled TikTok accounts (including @lavaxgrll7, @lavaxgrll0, @lavaxgrll20, @lavaxgrl, and @lavaagrl) and X/Twitter accounts (including @Lavaaxgrl, @Lavagrlx, @Lavaagrlx, and @lavagrll) also circulate. This research found no first-party hub confirming any single one of them as hers, so none is listed as a confirmed link here.
Scam & impersonation warnings
- Search results for her name and handle surface a large field of "OnlyFans leak"/"exclusive files" spam pages, including near-identical templates repeated across hijacked institutional (.edu-style) subdomains and spam postings on code-repository sites — a scam/SEO pattern seen across many creators' names, not evidence of any account she controls. None of it is linked or described further here.
- Lookalike or impersonator accounts across platforms may use her name, handle, and photos; only the account listed above, cross-confirmed against her TMZ- and IMDb/TMDB-documented identity, is treated as hers.
- No official AI-persona statement, platform AI label, or operator claim of a virtual model was found anywhere in this research; her IMDb/TMDB-credited screen appearances and named press coverage support a real human creator, not a virtual one.
The documented facts
- TMDB's own independently loaded cast page for the YouTube reality series The Reality House credits "Mariah" as "Self - Contestant" across 10 episodes, matching the widely reported third-season timeframe (premiered Nov. 19, 2021; concluded Jan. 22, 2022) alongside cast members including Tana Mongeau and Bryce Hall. Source: TMDB — The Reality House, cast · documented
- IMDb's own structured credit data — independently indexed by search engines, though IMDb's page itself returned an access-blocked response to this research's automated fetch — attributes that same "Self," 10-episode Reality House credit specifically to "Mariah Casillas," corroborating TMDB's independently loaded cast entry. Source: IMDb — Mariah Casillas · documented (search-indexed; IMDb's own page blocked direct automated fetch, corroborated by TMDB's independently loaded cast data)
- IMDb search-indexed data also credits "Mariah Casillas" with a role as "Diner Customer" in "42 Seconds" (2024), an independent short drama film shot in Superior, Arizona, written by Judith Eisenberg and directed by Steve Anderson — a second, separate screen credit distinct from the reality-show appearance above. Source: IMDb — "42 Seconds" (Short, 2024) · documented (search-indexed; IMDb's own page blocked direct automated fetch)
- TMZ (staff-reported, Aug. 21–22, 2023) reported that Mariah Casillas launched a GoFundMe campaign offering a nude photo per $10 donated to Maui wildfire relief; after GoFundMe removed the campaign and refunded roughly $7,800 in donations for a terms-of-service violation, she continued the fundraiser through her own OnlyFans account and raised more than $10,000 for wildfire relief, and appeared on TMZ Live that week to discuss it — a verified real-time media appearance.

- Instagram's own page metadata for the account @lavaxgrll displays the name "Mariah Casillas" — a self-configured display-name field on her own account, captured consistently across multiple independently indexed page snapshots including one from March 30, 2026. Source: Instagram — @lavaxgrll · documented (self-disclosed name field; login wall prevented independent real-time reconfirmation)
- Multiple aggregator and bio-farm sites describe her as the outright winner of The Reality House's third season; this research found no independently confirmable named-press or platform-official source specifically confirming winner status beyond the documented 10-episode cast credit, so the winner claim specifically is treated as reported rather than documented. Status: reported
- No official AI-persona statement, platform AI label, or operator claim of a virtual model was found anywhere in this research; her IMDb/TMDB-credited screen appearances and named press coverage are consistent with a real, documented human creator. Status: unknown
