UFC women’s bantamweight champion Ronda Rousey is known to partake in the occasional trash talk — and not just with her opponents.

But the target of her latest rant, published online today by Cosmopolitan, may surprise even the most cynical observer.

As it turns out, Ms Rousey is no Belieber.

That’s right, Canadian pop star Justin Bieber has incited the rage of Ronda Rousey.

She explains to the venerable women’s magazine:

My little sister is very hard to impress. We really didn’t care about anybody that was at the Cannes Film Festival, but I wanted to spend some time with her. Justin Bieber was over there taking some pictures with some ladies and she suddenly got really excited and was like, ‘Do you think he would want to take a picture with me?’ And I was like, ‘Sure Julie, everybody is taking pictures today, don’t feel bad about it at all. That’s why everybody’s here. Don’t worry about it, he’s a sweetheart.’

So I walked over there and I said, ‘Excuse me.’ And he said, ‘I’ve already taken a billion pictures today, Okay!’ And I’m like, ‘Yeah, but she’s the only 16 year-old at the party.’ I only got the ‘Yeah but’ out and he said, ‘A billion!’ And he walked way and totally snubbed my sister. She looks at me on the verge of tears and she goes, ‘I’m no longer a Belieber.’ Yeah, I don’t think I’d want to hang out with him. I’m not a Belieber. I was, but I am not anymore.
