Happy Birthday to Sophia Richie who celebrated her 21st birthday on Saturday. The model celebrated with her boyfriend of two years Scott Disick, plus Kylie Jenner, and friends in Las Vegas. Scott surprised her with a 200 thousand Aston Martin!
They then headed to the resort's XS Nightclub, where The Chainsmokers performed. The Chainsmokers' Drew Taggart later had Sofia join him on stage and had the crowd sing her "Happy Birthday."
