Sofia Richie proudly showed her tight figure in a revealing black string bikini on Wednesday when she went to Instagram to post the latest snap of the European escape from the Kardashians.

The model, 20, hissed in a skimpy black string bikini as she leaned back on the $ 250 million super yacht in the bright sun after it was docked in southern France.

Sofia is on the yacht with friend Scott Disick, 36, celebrating Kylie Jenner's 22nd birthday.

In no time, Sofia posed in a series of positions as she relaxed on the upper deck of her yacht with her peach-like back on display in the revealing two-part.

With her illuminated blonde strands in a straight, smooth style, the star wore sunglasses with a narrow frame while relaxing in the sun.

She kept the caption simple and wrote: & # 39; Let me go. & # 39;

Sofia and Beau Scott enjoyed the sunny vacation with Kylie while celebrating her birthday on the lush super yacht.

Scott recently praised his girlfriend – with whom he started dating in September 2017 – for the great support she gave him while working on his new show, Flip It Like Disick, which her & # 39; incredible & # 39; called.

He added to US Weekly: & # 39; & # 39; She doesn't really like architecture, so it's different, but she and I have a good relationship. & # 39;

Although they have great communication, the couple seems to share different tastes in home design.

& # 39; She likes a little more land, but I build houses to sell, not to live in, & # 39; he added.

Scott and Kourtney Kardashian, 40, dated from 2006 to 2015 for nine years and have three children, Mason, nine, Penelope, seven and Reign, four.
