Rihanna showed up at her 02 arena concert in London an hour late last Thursday and her fans boo'd her diva a*s! Fans stood waiting until 10PM before Rihanna began her setlist.

An angry concert-goer told Digital Spy: “She didn’t come on till 10, leaving the audience waiting an hour. She then got booed and her singing was rubbish. Apparently the rubbish concert "was unnecessarily raunchy and inappropriate." Sad! Brits aren't familiar with the Internet. Rihanna is always pretty much masturbating on stage every night because she's a hooker who works in the wrong profession.

The angry fan continued: "When we left halfway through the show, along with loads of other people, staff were handing out information on making complaints.”

This is not the first time Rihanna pulled this stunt in London. Last month she left her audience waiting 55 minutes before starting her show.
