MIAMI – Alex Rodriguez’s heartbroken wife Cynthia believes her hubby has been “brainwashed” by kabbalah-pushing pop icon Madonna and lured away from his family, an A-Rod confidant said yesterday.

In a bombshell interview with The Post, Dodd Romero – Rodriguez’s former trainer and godfather to his two daughters who spent last week in Paris with Cynthia Rodriguez – said he and C-Rod believe the Yankee superstar has been gradually drawn away by Madonna’s allure.

“Alex, God bless him, is lost,” A-Rod’s ex-pal lamented. “I think he got pulled in by the dark side, if you can say that nicely. He’s totally brainwashed.”

“She believes it’s what ruined her marriage,” Romero added.

A-Rod’s first encounters with the Material Mom came through their common friend, Miami nightclub owner Ingrid Casares, Romero said.

Once Madonna and A-Rod started working out together in New York in November 2007, he was under the complete spell of kabbalah’s most famous practitioner, the slugger’s confidant said.

“He’s more infatuated with the fact he’s with an icon instead of realizing what’s important, which is family and truth,” said Romero, 46.

“Alex [is acting like] he wants a divorce.”

The trainer said he severed ties with A-Rod shortly after Cynthia gave birth to their second child this spring.

Sources said Alex arrived in Miami just in time for the birth of Ella on April 21.

He spent as little as 10 minutes with mother and child, then bolted back to New York and straight to Madonna’s Central Park West pad, where he has allegedly spent a number of late nights.

Since then, A-Rod has seen his little daughter only a couple of times, said Romero.

Cutting off his relationship with A-Rod “was one of the hardest things I’ve had to do, because he’s like a brother to me,” Romero said.
