Model Sofia Richie, 20, flaunts her amazing figure in a tiny orange bikini on holiday with 35-year-o

According to reports Sofia Richie was said to be 'uncomfortable' at her boyfriend's cosy family pictures with his ex Kourtney Kardashian.

But It looked like 20-year-old Sofia Richie had brushed it off, as she enjoyed a holiday in Cancun

with her 35-year-old beau Scott Disick, his kids and their mother Kourtney Kardashian, 40, on Saturday.

Kourtney and Sofia seemed to be having fun together, as they lounged side by side on deck chairs, Sofia was pictured as she leaned over to look at something on Kourtney's phone.

Sofia showed off her fantastic figure in her orange swimwear and looked relaxed.

See pictures and video:

Checkout the video of Scott, Sofia and Kourtney shared by TMZ, they were seen at place called Edith's. Again, not a hint of animosity between the current/former couple.

My view: Wow Sofia Richie, 20, spending Christmas with her 35-year-old boyfriend Scott Disick and his 40-year-old ex Kourtney Kardashian and their kids, that's great isn't it.? I wonder if Kourtney will allow Scott to join her on holiday with her toyboy boyfriend?. It's good to see happy family together, but Sofia is just too young for Scott and Kourtney's gimmick, you need your space to enjoy your life with your boyfriend and his children without Kourtney in your face 24/7. Both Scott and Kourtney have enjoyed their time to together as a couple, so stop acting like parents to Sofia, or maybe the trio are trying to get their own reality show, Keeping Up With Scott, Sofia And Kourtney (KUWSSAK), since no one watches KUWTK anymore. Sofia Richie looks good and very natural, unlike the Kardashian/Jenner cosmetic surgery looks and physique, that they all continue to deny, especially Khloe Kardashian and her alleged cosmetic surgery or maybe she's very good at photoshopping. Kourtney looks good for her age though. Sofia is just being wise, as she doesn't want to give Scott alone time with his ex Kourtney.
