Justin Bieber, Selena Gomez 'split' over troubled celebrity friends

Justin Bieber and Selena Gomez are said to have split over the 'Baby' singer's troubled celebrity pals.

The young couple allegedly ended their relationship after Bieber attended a recent Gomez concert in Florida with R&B star Sean Kingston, who was jailed at the age of 11 for breaking and entering.

The Wizards Of Waverly Place star has also ordered the 17-year-old to avoid his showbiz friend Lil Wayne, who holds several gun and drug possession charges, and his 'Next To You' collaborator Chris Brown, who infamously assaulted ex-girlfriend Rihanna in 2009.

"She didn't want him to crash her gig," a source told The Sun. "They had a huge row and said it was good they were having time apart while she was on tour."

The insider also claimed that Bieber had been reduced to tears during the heated arguments, adding: "It's hard seeing a little 17-year-old crying and saying he loves her."

Gomez claimed this week that she tries to keep her relationship with Bieber as "normal as possible".
