Justin Bieber may just have messed with the wrong girl this time -- for UFC champion Ronda Rousey is NOT afraid to express her displeasure.
According to Movie Pilot, Ronda said that she's no longer a Belieber after the pop sensation snubbed her 16-year-old sis at Cannes Film Festival.
She recounted in an interview with Cosmopolitan:
"Justin Bieber was over there taking pictures with some ladies...
"...and suddenly she [Rousey's sister] got really excited and said 'do you think he'd wanna take a picture with me?' and I was like 'Sure Julie, don't worry about it'
"I walked over there and said 'excuse me'. He turns to me and goes 'I've already taken a billion pictures today, okay'
"And I said 'yeah but'...because she's the only 16-year-old at the whole party, you know? But I only got out 'yeah but-' and he goes 'a billion' and walks off.
"She looks at me and she's on the verge of tears, and she goes: 'I'm no longer a Belieber'. Yeah, I don't think I'd wanna hang out with him. I'm not a Belieber. I was, but not anymore..."
