LOTTIE Moss flashed her underboob and showed off her huge tattoo collection after being linked to Leonardo DiCaprio.
The 26-year-old, who is the half-sister of model Kate Moss, jetted off to Mexico for some winter sunshine to celebrate her birthday.
Lottie, 26, has been updating her fans with what she's been up to on her Instagram page.
The Celeb Go Dating star posed up a storm in a bright pink bikini.
Lottie showed off her natural beauty with not an inch of make-up and styled her blonde locks into plaits.

"Birthday b***h," she captioned the post.
It comes after Lottie was spotted out and about with American actor Leonardo DiCaprio last month.
It was alleged that the pair enjoyed a late-night date while Leo was in London to promote his film Killers Of The Flower Moon.
A source previously said: "Leo and Lottie were having a great time and seemed really close."
Lottie took part in Celeb's Go Dating last year alongside Chloe Burrows, Adam Collard and Vanessa Feltz.
The OnlyFans model struck up a romance with Geordie hunk Adam - and the pair seemed to really hit it off.
However things didn't last long after the cameras stopped rolling.
The Love Island legend later moved on with talkSPORT host Laura Woods.
