Washington Redskins star Albert Haynesworth is being sued for $10 million by a Brooklyn exotic dancer who claims he impregnated her — then abandoned her.

Salma Hayek look-alike Silvia Mena,who’s nearly four months pregnant, says she met the 6-foot-6, 350-pound defensive lineman in Miami late last year. But she claims in papers to be filed in Brooklyn Supreme Court he dumped her after learning she was expecting in late February.

The papers allege that Haynesworth — who signed a $100 million contract with the Redskins last year — has refused to talk to her since late March or give her any money toward her medical bills.

Mena, 25, alleges Haynesworth, 28, met her in Miami, romanced her during Super Bowl week, and invited her to his Tennessee home. She claims in the documents that after learning about the pregnancy, Haynesworth promised to “emotionally and financially support Silvia.” But, “after making such promises . . . Haynesworth has abandoned the pregnant Sylvia Mena . . . He has refused to provide any emotional or financial support of Silvia Mena or his unborn child.”

The papers read that Haynesworth’s assistant suggested Mena “seek treatment from an NFL physician.” But Mena feared “some effort might be made to purposefully make her lose the child,” the papers say.

Mena, who claims she has not heard from Haynesworth since late March, told us last night: “It is very stressful, I cry all the time.”

Her lawyer, Salvatore Strazzullo, told us he’s filing the $10 million suit in Brooklyn Supreme Court today.

“This man is worth millions,” Strazzullo said. “She has had to apply for Medicaid to take care of her pregnancy.”

Haynesworth’s agent declined to comment on Mena’s claims.
