Did he give the supermodel the boot? It appears that way!

Harry Styles hit up Clive Davis' pre-Grammys party this weekend, and we caught him leaving the bash with a mystery girl that most definitely isn't Kendall Jenner! Something tells us the One Direction star kicked her to the curb, because he was getting mighty close with this chick. They even left in the same car!

The British heartthrob and Kim Kardashian's little sister haven't really hung out that much since they went on a romantic Caribbean vacation together over Christmas, and it sounds like poor Kenny might just be the girl that's expecting too much from the guy that wants to keep it casual.

"At this point in her life, Kendall is ready for a serious relationship. She thought she could just go with the flow with Harry, but it’s just not making her happy. Harry is too loosey-goosey for her," a source dished to Hollywood Life.

"It’s pretty much what happened the first time around for them; Kendall wanted more and Harry wasn’t ready to fully commit. They aren’t on bad terms or anything, but Kendall isn’t going to wait around for Harry to make the next move, which would be to make a serious commitment and follow up with concrete actions. She wants a guy who’s going to walk the walk," the source added.

Another person he's pretty done with? Zayn Malik, who was at the same party! We wonder if the two were cordial and chatted briefly, or whether they avoided each other all night!
