Mel B is already getting smaller in Stephen Belafonte's rear view -- 24 hours after their divorce was official ... he hit the clubs!!!
We got Stephen outside Delilah in West Hollywood ... where he proudly yelled, "I'm free!" ... on his way into the club. On his way out, he tried to put on a more somber face. Tried.
First, he gave a shout out to Lupus research ... we're guessing it was a fundraising event at the club. Then he offered some marriage advice -- pretty much what you'd expect from a guy the day after his drawn out, nasty divorce ends.
But Belafonte couldn't keep the smile off his face when we asked about his New Year's plans. He's headed to Cabo and insists there won't be any chicks involved. But ... c'mon.
