According to TMZ, Brown was leaving Playhouse in the wee hours of Monday morning, but not under his own power. Brown's arms were squarely wrapped around the shoulders of two guys ... while a few other people cleared the way.
Tran -- Chris' on-again/off-again girlfriend -- was waiting in a sick orange Lambo ... ready to whisk CB away. No doubt he napped the whole ride.
Brown performed at the BET Awards earlier in the evening -- his first show since getting out of jail.
As TMZ previously reported, Brown emerged from jail earlier this month pledging he would change his partying ways and never go back behind bars. So much for that.
