BEN AFFLECK and Matt Damon may be best buds, but sources say their wives can’t stand each other!

“The two families socialize frequently,” an insider told The ENQUIRER.

“But despite Matt and Ben’s decades-long working partner­ship and friendship, their wives have never warmed to each other.”

TENSION REACHED A FEVER pitch after Ben, 40, won the Best Picture Oscar for his political thriller “Argo” with wife Jenni­fer Garner at his side on Feb. 24, sources say.

Just days later, Matt’s wife Lu­ciana Barroso pushed him into announcing they’re planning a destination wedding in April – more than seven years after they tied the knot at City Hall in New York City.

“Luciana has always felt that Matt is more talented and way more deserving of recognition than Ben,” an insider told The ENQUIRER.

“It burned her up seeing Ben feted for months like he’s the King of Hollywood.”

So sources say green-eyed Luciana, 37, goaded Matt – who shares a Best Screen­play Oscar with Ben for the 1997 drama “Good Will Hunting” – into sending out “save the date” invites to their wedding.

 “It was totally unecessary, BUT Luciana wanted to stick it to Ben,” said the source.

And even though Matt and Luci­ana have four children – her daughter Alexia, 13, and their girls Isabella, 6, Gia, 4, and Stella, 2 – while Jen and Ben have three – daughters Violet, 7, and Seraphina, 4, and son Sam, 1 – the wedding invite specified “no kids,” said the source.

“The no-kids rule was particular­ly stinging to Ben and Jen because it’s very unlikely Jen would ever leave their three kids behind,” said the source.

“She’s furious that Luciana and Matt even suggested it.

“So while Matt and Ben are still best buds, they’ve had to accept that their wives will never share the same close friend­ship.”
