[VIDEO] Rihanna Punches Karrueche Tran Look-A-Like? Hits Fan With Microphone During 'Diamonds' World Tour Concert And Says It Was On 'Purpose'

Rihanna throwing jabs at Karrueche Tran via social media is one thing, but punching a fan in the face with her microphone during her 'Diamonds' world tour is another.

During Rihanna's concert in the U.K., the singer went down to the fan level and let fans touch her, until one fan wouldn't let go of the "Umbrella" singer, yanking on her clothing. The Barbadian singer tried to pull her arm back and finally whacked the young fan with her microphone.

In the video, you can hear one fan yell, "what the f--k" and an "oh my god."

According to MTV U.K., one fan asked the singer if she accidentally meant to hit her fan and Rihanna tweeted, "Purpose! That b*tch won't let me go," but the singer deleted the comment right after.

Was Rihanna right for that?
