Harry Styles and Kendall Jenner: Overnight Weekend Hookup?

Harry Styles and Kendall Jenner's romantic weekend?

The Harry and Kendall dating buzz isn't slowing down after Harry was spotted at her London hotel over the weekend.

Did they have an overnight date...um...sleepover?

After One Direction appeared on the NRJ Music Awards in Cannes, Harry returned to London, where he was seen at Kendall's hotel at 2:20 a.m., either carrying a small overnight bag or a change of clothing.

Kendall was seen arriving at LAX early Monday after spending the whirlwind weekend with Harry--but was she in London just to see the 1D hottie or did she have a modeling gig?

The PR stunt rumors keep on rolling--why didn't Harry try to sneak into a back entrance of the hotel, instead of being in plain sight of the paparazzi?

Harry reportedly skipped out on the post-NRJ Awards celebration with his band to spend time with Kendall.

Do you think this is a fakelationship or are Harry and Kendall really dating?
