Harry Styles and Kendall Jenner are supposed to have a “thing” going on, but is it exclusive? If so, then some believe Harry is cheating on the model and Keeping Up With the Kardashians star.

A new report claims the former One Direction singer spent the night at his London home with 27-year-old stylist Pandora Lennard.

It was last weekend the alleged overnight took place, with Pandora staying until about noon the next day.

Meanwhile back in the U.S., Harry Styles and Kendall Jenner were spotted together in L.A. on Saturday evening, at music agent Jeff Azoff’s birthday party. Although the two didn’t arrive together, Harry and Kendall were very much together inside the bash.

Does Kendall know Harry Styles allegedly spent the night last weekend with Pandora Lennard?

It bears mentioning that no one has said Harry Styles and Kendall Jenner are exclusively dating. Perhaps they have one of those open relationships where both parties do as they please.

Kendall is headed off to Barcelona later this week. Maybe she just needed her Harry Styles fix to set off on her adventure.

What do you suppose the real scoop is between Harry Styles and Kendall Jenner? And how does Pandora Lennard figure into the mix?
