Marc Anthony I'm the Rebound King ... Ask My Smoking Hot 21-yr-old GF!

Marc Anthony's outdone himself again and wasted NO time doing so -- he scored a model barely old enough to order Jägerbombs, even before his divorce was final.

We're told the 48-year-old singer's been dating Wilhelmina Miami model Mariana Downing for a couple months now after meeting her at a dinner party. Witnesses say Marc was immediately smitten -- because he has eyes -- and they exchanged numbers that night.

We're told he called Mariana the next day and they've been together ever since. She's traveled with him to one of his shows, and they've vacationed together in the Caribbean.

Marc's divorce from Shannon De Lima was just finalized on Monday, but he's been on the market since they separated in November.

Von and his crew hopped on the train and rolled over to meet Odell ... because that's what you do when you're rich and it's the off-season.

Samantha won't say where she patrols -- only that it's somewhere in NY state -- but she has an interesting take on her uniform, and what it does for female cops ... fashion-wise.
