Scott Disick’s model girlfriend Amelia Hamlin posed for a risqué mirror selfie in a tiny black bikini top, after returning home from her romantic getaway in Cabo San Lucas.

After spending a few glorious days enjoying one of Mexico’s most beautiful beaches, the 19-year-old daughter of Lisa Rinna showed off her enviable tanned physique. 

In her latest snap on her Instagram Story, the beauty proudly displayed her gym-honed abs and midriff as she wore a pair of skintight black biker shorts.

While Hamlin hid her face behind her phone, she appeared ready to soak up the sun as she kept her black shades perched atop her head.   

While keeping her accessorizes to just a silver chain bracelet on her right wrist, she cheekily placed an emoji of a pair of eyes looking slightly to the side on her ample bust.

Over the weekend, the brunette bombshell posted a number of other steamy shots from her New Year’s Eve trip with Disick, 37.

Scott, who has three children with ex Kourtney Kardashian, split with Sofia Richie last summer after two years of dating. 

First linked around Halloween, things between Hamlin and Disick have continued to heat up as they have been spotted getting cozy in Malibu together and even went away to Santa Barbara. 

When Scott seemed to be in the market for a new house, Amelia was by his side as they fueled rumors they were scoping out a potential joint pad, albeit a very fast move.

‘People are judgmental’: Hamlin hit back at criticism of her relationship with Scott Disick, 37, in an impassioned Instagram post over the weekend

Amelia, who has fronted campaigns for Too Faced and Hudson Jeans, recently defended her romance with the much older Keeping Up With The Kardashians star, who has been known to have a predilection for younger girls. 

‘ppl r extra weird and judgmental these days…people can embrace themselves however they feel fit for them at that moment in time. people grow. people learn to love themselves more and more.’

Despite seeming to be all in with Disick, Amelia’s parents were not so sure based on his track record with public relationships as well as his seemingly playboy ways.    

On Christmas, the family celebrated without him even though sister Delilah Belle’s boyfriend Eyal Booker was present as they all dressed up in matching red pajamas.

A source told The Sun that Lisa and dad Harry Hamlin are ‘worried’ for Amelia.   

‘Sofia was a bit hurt that Scott was flaunting his relationship with Amelia Gray Hamlin so freely. Scott has been preoccupied with Amelia and Scott is the type of guy who can’t be alone and always needs someone there.’

Kardashian – who he shares Mason, 11, Penelope, eight, and Reign, six, is not bothered by the relationship at all according to the source. 

‘Kourtney isn’t bothered that Scott is hanging out with Amelia Gray Hamlin and is so far past thinking about him in a romantic way. She knows Scott better than anybody and she is supportive.’
