Rihanna managed to piss off her fans on Monday night after she came on stage at her London’s O2 arena show almost an hour late.

The Bajan bombshell was due to perform at 9pm but made her fans wait until 9.55pm before she emerged and was greeted by boos from the crowd. To make matters worse, when she finally did appear, her performance was less than impressive.

A fan told The Sun:

Fans weren’t happy at all. Especially as, when she did finally come on stage, her performance was half-hearted.

It’s no secret that Rihanna, who is currently on her Loud tour, has become a bit of a party animal and it’s been suggested that the singer could have been hungover for the gig, as she was spotted leaving London nightclub Whiskey Mist in the early hours of Sunday morning. Not very professional Ri-Ri.

She also seems to be ignoring the doctors orders to stay in and rest since she fell ill and had to cancel two shows in Sweden a couple of weeks ago.

The Umbrella singer has plenty more performance dates in the UK. Let’s hope that when she returns she puts a bit more effort into her time management and her performance.

What do you guys think of Rihanna’s shabby behaviour?
