In a recent interview with Cosmopolitan, Ronda Rousey revealed why she and her younger sister are no longer fans of the "What Do You Mean" singer, Justin Bieber.

"Justin Bieber was actually really rude to my little sister at the Cannes Film Festival," Rousey told the Cosmopolitan reporter.

As stated in the interview, Rousey took her sister to the event in France. Although the event was filled with celebrities, the younger singer was "very hard to impress" and only came alive when the 16 year old saw Bieber.

Rousey told Cosmopolitan, "Justin Bieber was taking some pictures with some ladies and she suddenly got really excited and was like, 'Do you think he'd want to take a picture with me?'

During the interview, Rousey stated that she reassured her younger sibling saying that since it was a media event "everyone's taking pictures today... that's why everybody's here" and that Bieber was "a sweetheart."

As Rousey proceeded to ask for a picture, Bieber turns around and says, "I've already taken a billion pictures today, OK." According to the magazine's interview with Rousey, Bieber then reiterates the words "a billion" before walking off.

"She looks at me and she's on the verge of tears and she goes, 'I'm no longer a Belieber.'" Rousey shared the same opinion to the reporter stating, "Yeah I don't think I'd want to hang out with him."

"I'm not a Belieber. I was, but I'm not anymore," Rousey stated in the interview.

Hollywood Life has stated that so far Bieber has not made any attempts to apologize or make up for snubbing the pair at the media event.

The Hearld Sun speculates that the Bieber was not aware of who Rousey was during the event. A similar incident occurred with his close pal and boxer Floyd Mayweather.

Earlier this year, the female mixed martial artist made a statement that she could beat the boxer. In the same report, the unbeaten boxer responded, "I don't even know who he is," erroneously referring to Rousey as a guy.

Daily Mail has recently reported that Rousey is currently busy promoting her upcoming championship fight against Holly Holm. The fight for the UFC Women's Bantamweight title is set for next month in Australia.

According to the Rolling Stone, she has also appeared on The Tonight Show Starring Jimmy Fallon donning a sleek black dress. During the interview, she talks about her upcoming fight and challenging Fallon to a Mario Kart rematch.
