Steve Granitz/Kevin Mazur/WireImageRonda Rousey is the UFC Women's Bantamweight Champion —the last thing anyone wants to do is get on her bad side…but leave it to Justin Bieber to do just that.
The 28-year-old UFC GOAT told Cosmopolitan magazine this week that the pop crooner pissed her off at the Cannes Film Festival when he was rude to her little sister.
Rousey explained how her 16-year-old sibling was pretty unfazed by anyone at the festival…with the exception of Bieber. Unfortunately, when Rousey went up to the singer to ask for a photo for her little sis, the Biebs completely blew her off.
"Justin Bieber was actually really rude to my little sister at the Cannes Film Festival," she told Cosmo. "My little sister is very hard to impress, and so she really didn't care about anyone who was [there], but I wanted to spend some time with her."
She continues, "Justin Bieber was over there taking some pictures with some ladies, and she suddenly got really excited, and she was like, 'Do you think he would want to take a picture with me?' And I was like, 'Don't worry about it…Look at him! He's a sweetheart!'"
However, when Rousey walked over and asked for a photo, he gave her the cold shoulder
"He was like, 'I've already taken a billion pictures today, OK? A BILLION,'" Rousey recalls. "He walks off and totally snubbed my little sister, and she looks at me, and she's like on the verge of tears, and she goes, 'I'm no longer a Belieber.'"
At that moment, Rousey admits she, too, stopped beliebing.
"Yeah, I don't think I'd want to hang out with him," Rousey notes. "I'm not a Belieber. I was, but I'm not anymore."
Rousey is too busy making history to worry too much about Bieber anyway. This week she made headlines for her cover on Australia's Men's Fitness magazine—the first time a woman has ever been front and center for the publication.
The magazine hits newsstands Thursday.
