Justin Bieber has apparently caused a bit of drama in Kamp Kardashian of late - after Bruce Jenner demanded that daughter Kylie Jenner stay away from the swaggy singer.

According to an so-called 'insider', Bruce 'hit the roof' when he discovered Kylie had gone to Las Vegas with El Biebs, because he's concerned she'll be influenced by his alleged drug use and general bad behaviour.

Yes, we've heard that weeing in mop buckets is pretty contagious. Lolz.

"Bruce had thought Justin was hanging out with Kendall, his 18-year-old daughter, with Kylie just tagging along and he was fine with that," said the source.

"But when he learned that Bieber had taken Kylie to Las Vegas to see the Floyd Mayweather Jr. fight, he hit the roof and immediately called estranged wife Kris Jenner, fuming.

"Bruce then phoned Kylie, forbidding her to date Bieber ever again bluntly declaring her doesn't want her influence by his drug use and bad behavior.

"Kylie went crying to Momma, but Kris - who's usually all about the publicity - shocked her by siding with Bruce. She totally agrees Justin's bad news."

This news comes after Kylie posted a snap in which she's seen looking pretty cosy with Biebertron. OH THE SCANDAL. What do you make of all this?
