Justin Bieber Apologises to Ronda Rousey for Sister Snub: 'Don't Kick My Ass!'

Justin Bieber has moved to cool any tension between himself and Ronda Rousey after the UFC fighter accused him of snubbing her teenage sister at the 2014 Cannes Film Festival.

Rousey then decided she was no longer a fan of the Canadian pop star and wanted an apology.

In an interview with Elvis Duran on Entertainment Tonight that airs Wednesday, Bieber obliged, per the Belfast Telegraph.

"I guess, supposedly, she asked for a picture with her sister or something, and I guess I said no?" he said. "But I don't remember this happening so, Ronda, I'm sorry. Don't kick my ass!"

Just minutes later, he apparently gave Rousey another reason to be mad, as he brought up her loss to Holly Holm over the weekend.

"Did you see Ronda Rousey?" he asked. "She got knocked out cold! Oh my God, she got knocked out so bad. Yeah no, she got pummeled."

Some classic diplomacy at play there from the Floyd Mayweather Jr.-trained singer.
