Justin Bieber apologises to Ronda Rousey over photo snub, then disses her

Seems Justin Bieber spends as much time apologising as he does performing these days.

The latest "I'm sorry" recipient is Ronda Rousey. Last month, the 28-year-old UFC mixed martial artist slammed the 21-year-old pop star for refusing to pose for a photo with her little sister earlier this year at the Cannes Film Festival.

According to Page Six, Justin didn't leave his Ronda commentary to a simple apology during the interview. When asked about his non-musical aspirations, he let the catty out.

"I would like to get better at boxing…Did you see Ronda Rousey?," he said, referring to the match earlier this week in which she was defeated by Holly Holm. "She got knocked out cold! Oh my God, she got knocked out so bad. Yeah no, she got pummeled."

Way to ruin an apology, Justin.

We're pretty sure it won't be long before he's apologising for that, too.
