You know Bow Wow must have been effed up if Chris Brown was the voice of reason on New Year's Eve!

Bow Wow took to Twitter to brag about being "young", "rich," and "f*cked up" while driving, and apparently pal Chris Brown, who was also at the Fontainebleau Miami Beach's LIV Nightclub, was the one who was trying to calm him down!

"Im bout to be f*cked up n drunk tweeting. Im saying sorry now for what i might tweet. But f*ck it ! Im young n rich im goin hard 2nite," Bow Wow tweeted from the party.

"He was out of control," one partygoer told the NY Daily News. "Chris seemed like he was taking care of him - he had two security guards with him at all times and was making sure Bow Wow didn't do anything too stupid."

But apparently there was a huge FAIL, because minutes later Bow Wow tweeted, "Face numb im whippin the lambo. Tipsy as fuck. Just left the @livmiami Im fucked up!!! Ohhhh damn. Y i drive the lambo. Chris might have to drive after next spot"

One witness says, "The valet looked skeptical and asked him if he was okay to drive. But Bow Wow didn't look happy that he asked that - and the valet just gave him his keys. It would have been a huge scene if they denied him his car."

It would have been a bigger scene if they had gotten into a wreck!

But clearly everything turned out fine, because the next day, Bow Wow tweeted, "Apologize for that tweet. it was stupid and immature. not a way i want to kick my #2010 year off. i got too much good stuff lined up. my bad"

Bad Bow Wow indeed!
