The soon-to-be 21-year-old showed off her toned abs and legs as she headed out for an early birthday lunch with her brother. 

Looking casual, the model paired a grey knit mini skirt with a white cropped tank. 

Sofia's blonde locks flowed in the breeze as she went retro in neon green and grey sneakers, with above the ankle white socks.

Sofia began dating Scott in 2017, they made their relationship Instagram official in September of that year. 

The pair even now live together at Scott's home.

She was even onboard as Kylie chartered the $250 million super yacht to whisk her loved ones between such locations as the Amalfi Coast and Portofino in Italy.
