Justin Bieber caused Kerr-Bloom split?

Kerr, 30, and Bloom recently ended their three-year marriage and in a joint statement announced that it was an amicable decision. They have a two-year-old son Flynn.

Kerr is said to have spent time with Bieber, 19, at a party in New York nearly a year ago, reports dailymail.co.uk.

She was pictured snuggling up to the singer in an eye-popping ­gem-encrusted green corset after a Victoria's fashion show in 2012.

"Orlando heard that there had been some ­flirting ­going on and he wasn’t exactly thrilled about it," said a source.

"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.
