Dec 03, 2011 - Don’t be surprised if you see bags under Rihanna’s eyes when she takes to the stage at this weekend’s Capital FM Jingle Bell Ball in London - an 'exhausted' RiRi hasn’t slept a wink in 48 hours after a hellish stint of work.
Apparently the newly blonde 23-year-old has been a bit moody with those around her as she filmed the video for new single, You Da One, this week. A source said: ‘She was complaining she hasn’t had any kip in days and was a bit crabby.’
The We Found Love singer has been told to reign in the wild partying after a recent spate of health scares that put Rihanna in hospital on a drip.
There doesn't seem to be much chance of the singer slowing down any time soon as she is bound to be celebrating her four Grammy nominations.
Following the good news, Rihanna tweeted: ''#GRAMMYS2012 5 nominations!!!
