We're told he called Mariana the next day and they've been together ever since.
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.
His divorce from wife number four, Shannon De Lima, was finalised on Monday.
But it appears Marc Anthony, 48, has wasted no time moving on, as he is said to have been dating 21-year-old model Mariana Downing for a couple of months.
