Ben and Ana's First Big Fight

She's already had it with his whining-insiders

- 

THE honeymoon’s over!

Just weeks after winging with his gorgeous new galpal to Havana, Cuba, to meet her parents, Ben Affleck and Ana de Armas are slinging the mud in their first big blowout!

The ugly showdown was caught on camera as the aging beefcake and his brand-new brunette beauty shared an uneasy weekend stroll through Hollywood.

“Things were obviously tense between them,” said a spy on the scene. “They traded some very sharp words, and the rest of their time together was extremely icy!”

While the hunk’s reps insist everything is fine, insiders said Ben’s constant brooding was wearing thin on Ana, who let him know in no uncertain terms she’s finding him a drag to be around!

“They had a lot of fun to start off with, but he has so many issues and there’s serious talk Ana’s having second thoughts now!”
