Lottie Moss sets pulses racing as she models two figure-hugging red dresses for Outcast - just in time for Valentine's Day

Lottie Moss sent temperatures soaring as she posed for a sizzling new phootshoot for Australian fashion brand Outcast.

The former OnlyFans star, 27, slipped into two figure-hugging red dresses just in time for Valentine's Day. 

One garment featured a high collar along with a cut out detail across the chest and a ruffled embellishment. 

The second included a tasteful off-the-shoulder detail while still encoroprating a vivid red Valentine's Day colour scheme.  

Showing off her array of tattoos, Lottie added height to her frame with a pair of black heels while perched on the edge of a bathtub.

Letting her blonde locks fall loose down her shoulders, Lottie - who is the younger sister of Kate Moss - completed her look with a light palette of makeup.         

It comes after Lottie broke down in tears on Celebrity Bear Hunt as she opened up on her failed rehab stint for substance abuse and depression that 'didn't work'.

In emotional scenes, the star couldn't keep it together as she candidly told her co-stars that her 2022 stay 'didn't work' and she was about to go into rehab again before starting the show.

Opening up to her co-stars on the Netflix series, Lottie said: 'Drugs and depression. You become quite numb. I didn't feel anything. I didn't care if I lived or died.

'I would have run it into the ground to be honest and my mum said, "You need to go into rehab'"

The younger sister of Kate Moss explained that it 'made her feel better but it didn't really work'.

TV personality Steph McGovern asked her what did work and Lottie honestly told the group: 'Nothing. I'm not going to lie to you guys, before coming in here I was about to go to rehab again.'

As she made the brave admission, she couldn't hold back her tears and put her face in her hands as she began sobbing.

'I'm going to get emotional,' she warned, but her campmates rallied around her to give her support and encouraged her to 'let it out'.

Lottie did a stint in rehab in February 2022 for substance abuse issues, specifically with cocaine, at an unspecified facility in the U.S. 

The model says she never touched drugs or alcohol before becoming a catwalk star but later became hooked.

And the London-born socialite revealed she never felt able to confide in half sister Kate Moss about her troubles, admitting the endless comparison with the supermodel was a constant burden during her career. 

Previously speaking in depth about her drug woes, Lottie said: 'I started quite early on with using drugs and alcohol as a crutch, as a coping mechanism, which there is not a lack of in the fashion industry.

'There were people in positions of power that were giving me drugs and alcohol when I was very young and so it didn't seem bad to me.' 

She continued: 'When you have people around you who are enabling you, I am talking at high fashion events and people are in a penthouse suite, and its people that are working for a brand that is very well known and they're sat there doing drugs with you as a 19-year-old.

Lottie 'That is so weird to me now… that should never happen in any industry.'

'The fact that no one said, 'maybe we shouldn't be enabling our client to do drugs. We should want her to be on her A game and doing her best, wake up in the morning and do a gym class, instead it was lots of alcohol', and it goes hand in hand.'
