I really think it must be something they put in the water that makes all these stars run from rehab. Robbie left rehab and then went out clubbing with friends here in LA. The article calls them mates which translates to guys. BUT, remember if you so much as insinuate that Robbie is gay he will sue you. Therefore, you call them mates. Everyone knows they are guys but could also be women. Robbie also enjoys scribbling on his knuckles. I guess he did not get the Britney memo though. Pssst, Robbie. Ummm, Britney's were just pen. You got a tattoo you idiot.
