They’re at it again. Scott Disick, 34, and his 19-year-old girlfriend Sofia Richie kissed for the cameras on Friday, Dec. 8, while attending an Art Basel party at one of his favorite restaurants, Sugar Factory, in Miami. In a surprising turn of events, Kris Jenner‘s boyfriend, Corey Gamble, had a front row seat to their PDA.

Though both Scott and Sofia slurped on brightly colored drinks, there wasn’t any alcohol in their glasses, according to People magazine. Lionel Richie’s youngest daughter is reportedly a good influence on the father-of-three, and he doesn’t feel as restrained when he’s with her as he did with ex Kourtney Kardashian.

“Kourtney and the Kardashians always tried to control Scott, unlike Sofia, who gives him the freedom he needs and lets him be himself,” an insider recently told In Touch. “Scott feels that Sofia is the only person who understands him.” Even though the duo’s age difference has raised eyebrows, “Scott says he’s dead serious about Sofia, that she’s here to stay, and is someone he’d like to start a family with.” The reality star already shares sons Mason, 7, and Reign, 2, and daughter Penelope, 5, with Kourt.

The twosome recently sparked engagement rumors when Sofia was spotted sporting a suspicious-looking ring on THAT finger. But one person who doesn’t buy their relationship? Lionel. The legendary singer seemed pretty convinced the duo won’t last. “C’mon, she’s 19,” he told Life & Style of his daughter. “She’s going to go take the turn and get through it and come out the other side… It will course itself.”

Well, as of right now, Sofia’s acting like a lovestruck teenager (oh wait… she still is one!) The model even has her boyfriend’s face on her phone case — specifically a photo from when he was still dating Kourtney! Hey, at least they haven’t gotten matching tattoos… yet.
