London: Pop star Justin Bieber`s growing friendship with Miranda Kerr is being cited as one of the reasons behind her separation from Orlando Bloom.
The 30-year-old supermodel, who parted ways with Bloom, 36 recently, was pictured getting cosy with Bieber, 19, after a Victoria`s Secret fashion show last year, reported Daily telegraph.
Bloom, who has a son Flynn with Kerr, was apparently unhappy when his son was taught to say `Bieber fever`.
"Miranda had always claimed that she was a fan of Justin`s music. She has taught her son how to say Bieber fever but it is supposed to have caused an issue," the source added.
The couple, who recently ended their three-years-old of marriage, announced that they have `amicably separated`.
