The model turns 21 this Saturday, August 24, and her Keeping Up with the Kardashians lover, 36, is sure to be planning a big birthday party.
Beautiful blonde Sofia's appeal to Kourtney Kardashian's ex is obvious!
Singer Lionel Richie's daughter has been modeling for years and knows how to show off all her sexy assets.
As Scott's galpal, she's become a paparazzi favorite and she also constantly posts photos of her body on Instagram.
Sofia is known for wearing thong bikinis, tank tops, tight pants, cropped shirts, and other body-baring clothes in photo shoots and on vacations with her main man.
On their latest getaway, to Italy, Scott's girlfriend left little to the imagination, oozing sex appeal in a string bikini.
She's had multiple nearly nude moments in her time with Scott.
Fans were shocked when Scott's on-again, off-again relationship with baby mama Kourtney finally ended and he started seeing Sofia in May 2017. She was only 19 at the time.
Since then, they've celebrated their love with PDA all over the world!
Followers of Sophia's Instagram account think Scott is one lucky guy to have the sultry model by his side.
And now, she's finally turning the legal drinking age!

Fun In The Sun
