Is Sofia Richie in love with Scott Disick? She appears to have fallen hard for the reality star. But she may end up hurt in the end.

Scott and Sofia were first linked late last month, and they have been spending a ton of time together ever since. Within days, they were posting photos of each other on social media and eating a mysterious "congratulations" cake.  One source told TMZ that they were celebrating becoming boyfriend and girlfriend.

Then the couple enjoyed a steamy vacation in Mexico. And Sofia hopes their relationship turns into something more. "Sofia calls Scott her boyfriend," a source told People. "She thinks he is the best."

The feeling may not be mutual, however. For Scott this seems to be a fun fling. "Scott likes her, but still says it’s not serious," the source continued. "Sofia hasn’t met his kids."

That's because he still has feelings for his ex, Kourtney Kardashian. But there is little chance Scott and Kourtney will get back together anytime soon. Kourtney has clearly grown tired of Scott's antics. And she is dating a hot young model, as well.

She has been hooking up with Younes Bendjima since May and their relationship has heated up since then. They hung out in the water in Cannes back in May and went on a vacation to France in July. More recently, they attended a chili cook-off in Malibu last month and partied in Paris during Fashion Week.

Ironically, Younes used to be friends with Sofia. But insiders told Us Weekly that Sofia and Younes are no longer in contact and have even unfollowed each other on social media.

Scott is jealous. But neither Scott nor Kourtney's current flings seem that serious. Instead, Sofia and Younes are just fun distractions. One insider even told People that Kourtney "likes her relationship with Younes, because it’s all fun and play.”

Of course, Scott also loves partying with other women. In an upcoming episode of Keeping Up With The Kardashians, Kourtney laments how her ex is "photographed with a different hooker every day."

So it's no wonder Sofia Richie's dad, Lionel Richie, is worried about his daughter. When the new American Idol judge was asked about Sofia's fling, he told Us Weekly, "Have I been in shock?! I'm the dad, come on." He added, "I’m scared to death, are you kidding me?"
