Lionel Richie once said that he's "scared to death" of his 19-year-old daughter dating the 34-year-old Scott Disick and unfortunately for him their romance is not slowing down. 

Sofia and Scott attended DuJour magazine's Art Basel party in Miami last night, since Sofia is the latest cover star, and although they never posed on the red carpet together, sources in attendance tell People that they were "chatting and kissing throughout the night" while being "very touchy."

As it's already known, Scott has three children with his former, long-term girlfriend Kourtney Kardashian. No official word on whether Sofia has been introduced to Penelope, Mason or Reign but with how long they've been dating and how open they are with their affection it may be sooner than expected. “Scott is telling friends that he’s in love with her,” a source told US magazine. “They are still going very strong.” Sources tell the publication that the duo spent the day lounging beachside with friends before the event.

I wonder how Lionel's feeling now?
