"The woman accused of stalking and blackmailing Yankees GM Brian Cashman has injected steroids into the sordid mix.

From Rikers Island, Louise Meanwell claimed Wednesday that Cashman told her he misled federal investigators over what the Bombers' brass knew of steroid use by players.

Meanwell, who claims she had an affair with Cashman, told the Daily News that Cashman confided to her that he was grilled in June or July by "the feds."

She said Cashman told her he made it seem like the Yankees had no knowledge of players' steroid use when, in fact, they did.

Cashman's spokesman Chris Giglio vehemently denied the accusations."
