Ronda Rousey, UFC's undefeated bantamweight champion, went to this year's Cannes Film Festival with her little sister, Julia.
Julia is 16 years old. All she wanted was to have a good time at the festival and take a single, innocent photo with America's sweetheart, Justin Bieber.
Ronda assumed it wouldn't be a problem for Justin to take a picture with her younger sister.
Apparently, Ronda was wrong. When she asked Justin for a photo, she said he gave her a pretty rude reply.
You can listen to Ronda talk about the encounter in the video above, but it's safe to say Ronda and Julia are no longer Beliebers.
