Despite recent events, it looks like Justin Bieber still has his fans, especially among the celebrity crowd. The singer cooled off from all the PR and legal problems he’s been having with a party in Ibiza on Friday night. And according to an ever trustworthy “unnamed source” for The Sun, he was joined by – get this – the latest PR project of the Kardashian-Jenner clan, Kendall Jenner.

Is JB making the moves on Kendall? We can't see it, but the rumour is going strong.

The young celebs attended a party for the birthday of Givenchi designer Ricardo Tisci. The guestlist also included Kim Kardashian and Kanye West (naturally), as well as Naomi Campbell, Jared Leto, P Diddy (or whatever he’s called these days) and Kate Moss – a fashionable crowd.

But back to JB and Kendall - the pair were apparently seen flirting throughout the night and then left together, The Sun reports.

"Kendall and Justin were inseparable for most of the night. Justin has always been good friends with the Kardashians, so he and Kendall go way back,” the source said. "As soon as Justin arrived he made a beeline for Kendall the moment he spotted her.”

The Biebs and Kendall apparently go way back.

Oh, but that’s not where the story ends. Well, it sort of is, because the details are preeetty sketch, but here’s what the source said about the rest of the evening anyway: "They were seriously flirting and kept going in and out of a photobooth together. There was lots of laughing and teasing and they were taking endless selfies.”

"After partying for about two hours they quietly slipped out of the party together and were seen holding hands."

It’d be pretty romantic, really, if it wasn’t for the mild “PR stunt” vibe of the whole thing. Anyway, new celeb couple? To be determined.
