Rihanna was booed by fans at her London gig on Monday night (14Nov11) after taking to the stage nearly an hour late.
The Umbrella hitmaker was due on stage at the O2 Arena at 9pm local time, but the performance didn't start until just before 10pm, and frustrated gig-goers showed their displeasure by heckling the singer.
A source tells Britain's The Sun, "Fans weren't happy at all. Especially when she did finally come on stage, her performance was half-hearted."
Rihanna previously apologised to fans at another gig on her Loud tour after showing up 90 minutes late to her show in Belfast, Northern Ireland in September (11).
