Bieber was forced to apologize.

The Purpose performer told Entertainment Tonight: 'I guess, supposedly, she asked for a picture with her sister or something, and I guess I said no?' he began.

But then he started criticizing her career.

In the same ET interview he said he wanted to get improve his skills in the ring.

'I would like to get better at boxing ... did you see Ronda Rousey? She got knocked out cold! Oh my God, she got knocked out so bad. Yeah no, she got pummeled.'

He was referring to Ronda's 2015 fight with Holly Holm, which she badly lost.
