Reality TV star Kylie Jenner has reportedly been banned from seeing singer Justin Bieber by her father Bruce Jenner.

The 16-year-old's father is not happy with her hanging out with the troubled singer, who has had numerous run-ins with the law this year and is again in the news for using a racial slur in a video.

The father doesn't want her seeing the singer again after she accompanied him to the Floyd Mayweather boxing match in Las Vegas on May 3 and to the Rainbow Room bar in Hollywood on May 27, reports femalefirst.co.uk.

"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 a 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 he doesn't want her influenced by his drug use and bad behaviour," added the source.

Kris is said to be supportive of Bruce's views and agrees she is too young to be hanging around with the 20-year-old.

"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," said a source.
