The newly blonde Rihanna and friends were spotted leaving Greystone Manor nightclub in West Hollywood last night (February 5, 2012) and judging from these hot & sweaty photos, they had the time of their lives.

The 23 year old diva, rocked a black leather Chanel biker style hat and revealing panel bodysuit paired with ripped jeans and is said to have been stumbling drunk as she exited the club hand in hand with her assistant and escorted by a police officer.

There was also talk that her ex-boyfriend Chris Brown was in the same club that night but he left via a side exit. Maybe she was asking the cop which way he went.

Could C-Breezy be mending Rih-Rih’s broken heart?
