Lottie Moss has told fans she's currently in rehab via a series of TikTok posts.
The younger sister of supermodel Kate Moss took to the app on Tuesday to update 21, 900 followers about her treatment.
The model - who in the past has claimed she loves OnlyFans because she likes being "drunk and stoned at work" - also revealed to fans that she was "not in the priory".
Wearing a black T-shirt bearing the slogan "Use a condom", Lottie, 24, posted two lighthearted videos from what appears to be the rehabilitation facility she's currently residing in.
Making reference to HBO hit Euphoria - a series with drug-related storylines - the OnlyFans creator quipped: "I think I took euphoria too literally u guys." [sic]
In the video, Lottie can be seen mouthing and swaying along to Labrinth's Mount Everest with the text "When everyone's glamourising droog [drug] taking but you're literally in r3h4b [rehab]" visible at the top of the TikTok.
The deliberate misspelling of words like 'drug' and 'rehab' is common practice by TikTok users to avoid the platform flagging your post or removing it entirely.
In another clip - filmed in the same room - Lottie makes light of her smoking habits and need for frequent breaks outside to light up.
"The staff at r3h4b [rehab] when i go outside for the 10000th time to $mok3," the caption reads across the video.
In the clip, Lottie mouths along to audio which includes the line: "If you're offended by a f***ing cigarette, you might as well jump off a cliff now."
"Do they sell cigs in there like how do you get them," one fan asked Lottie in the comments, to which she replied: "I brought in a brick x."
In another comment, one TikTok fan quipped "I know priory interior when I see it" but was corrected by the star.
"Nope not that place," Lottie replied - adding a shocked-face emoji to her comment.
The Mirror has approached representatives of Lottie Moss for comment.
Speaking in the past, Lottie has claimed she enjoys producing OnlyFans content because she likes being "naked, drunk and stoned at work".
Sharing a snap on Instagram, the model once wrote: "When people ask me why I do Only Fans I simply tell them – because I get to be naked, drunk and stoned at work."
After revealing her rehab stay on TikTok, Lottie liked a number of supportive comments from her followers.
"Sending you loads of good energy," was one message to get a like and acknowledgement from the model on Monday.
Elsewhere in the comments, a few TikTok users likened Lottie's journey to catwalk queen Kate's past struggles.
"Nah your sister covered that storyline," one blunt observer wrote, with another adding: "The addiction gene exists bro."
Kate - who shares the same father as Lottie - once famously checked into rehab after drug allegations in 2005 and is now said to be sober from from alcohol and all narcotics.
While Lottie didn't like or acknowledge either comment about her sibling's similarity, she did however like a comment from a fan which read: "She seems sm [so much] cooler than Kate."
