This could be the week that pushes Rihanna over the edge into rehab. At least I hope it puts her into rehab. The singer, who already blew off one huge project this summer has now told record label bosses that she won't be working for awhile and is not interested in going on tour until she has some fun. By fun, she means another vacation. Umm, she just got back from Barbados and is now in Italy where she has already been spotted getting wasted out of her mind on drugs and booze and also having sex with Drake and others. Yep, more than one. It is like one big orgy fueled hedonistic summer party. So, in other words she is living like a rock star. Huh.
