Is there trouble in paradise?

Sofia Richie got all glammed up to hit the Oscars parties last night, but boyfriend Scott Disick was noticeably absent! The teen model spent the evening with her dad Lionel, but it has us wondering if the two are having problems?

It can't help their relationship that LD is apparently still hung up on his ex Kourtney Kardashian and her new romance with Younes Bendjima.

"Scott is still insanely jealous of Younes. He just can't come to terms with the fact that Kourtney has found true happiness with someone else," a source told E! News.

"It makes things between them tense and unpredictable. Kourtney never knows when he is going to fly off the handle or go nuts about something. Scott just never thought it would last this long with Younes or become so serious. Nobody really did. Scott is hurt she chose someone else and it really bothers him. He can't control his emotions about it and lets it all out," the source added.

Speaking of The Lord, we caught him picking out some fancy cheeses at a shop in Calabasas over the weekend. Oscars party for one?
