*Rihanna’s fan club could be losing members.

The singer was booed when she showed up on stage an hour late at London’s O2 arena on Monday (Nov. 14) night.

When she finally made her appearance, concert-goers were quite upset and made it known. A source told Britain’s The Sun:

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

The gig immediately preceded Rihanna’s wild night on the town where she reportedly partied with over 20 bottles of alcohol before dishing out unsolicited sex advice to club-goers.

The event came after a slew of cancellations of the European leg of Rihanna’s tour due to over-exhaustion and an emergency trip to the hospital.

She also showed up 90 minutes late to her show in Belfast, Northern Ireland back in September.

RiRi is certainly looking pretty slump lately. Hopefully she’ll get on the good foot before her fan club dissipates.
