Rihanna seemed to be doing cocaine in a club, shows up 2hours late for England Show. Fans go crazy

Rihanna certainly pissed off many of her fans who attended her concert in Birmingham, England recently.  She was spotted out on Sunday night partying with model Cara Delevigne in London -- the day before she was scheduled to perform at 8 p.m. in Birmingham. Delevigne was allegedly spotted with "white powder" smeared across her lap when she exited the club.  

Rihanna apparently partied until around 3 a.m., which resulted in her showing up to her performance 2 hours late and she didn't end up taking the stage until around 10:30 p.m.  Her fans were not happy and expressed their disappointment at her lack of punctuality on Twitter.
