Bullet Proof Rihanna Is at It again!!!! see PIC

Spotted!!!! Super star , Rock-star "Bullet proof Rihanna" is at it again!!! 

TOO much boozing catches up with everyone in the end!!! Lol ! She never fails to stun everyone with her spontaneous activities  and personalities *wink* 

The singer is so worn out from partying that she's asking for a bed on shoots so she can take regular naps. A king size was installed in the corner on set of the video for new song Where Have You Been in LA this week.
 A reliable source confirmed that the "birthday Cake chick" has
 been hitting the party circuit hard and has been pretty knackered during the day.
She doesn't cancel any work commitments so she has stipulated that a king-size bed be on shoots so she can snooze betwen takes.
