from www.thehollywoodgossip.com – Pittsburgh Steelers quarterback Ben Roethlisberger is hitting back against sexual assault accuser Andrea McNulty, saying she is lying and mentally unstable.

The NFL star’s lawyer unloaded serious allegations at McNulty, claiming she bragged about sleeping with Ben and told pals she “hoped” he knocked her up.

In legal documents filed Friday in Washoe County, Nevada, Ben’s legal squad went after McNulty’s “false and slanderous” claim – and insists she “boasted to her friends and co-workers that she had consensual sexual relations with Mr. Roethlisberger.”

On top of Andrea “being happy” about sleeping with him, Roethlisberger claims after the incident, McNulty “was also not afraid or apprehensive about the prospect of an unplanned pregnancy, but expressed that she hoped that she was pregnant.”

Ben’s portrait of Andrea McNulty only gets worse.

Ben blames Andrea McNulty’s “alleged problems – lack of job security, need for medical benefits, need for treatment, increasing debt and lack of income” – on her “inability to do her job” at Harrah’s Casino in Lake Tahoe, Nevada:

“[McNulty’s] psychological breakdown appears to be the sad by-product of an affair with a married man whose wife concocted a scheme to have [her] fall in love with a fictional soldier and be abandoned by him to create heartbreak and instability.”

The document wasn’t just an excuse to bash Andrea McNulty.

Ben’s lawyers have requested to move the case out of Washoe County, Nev., “for the convenience of all parties and witnesses and in the interest of justice.”

So far, the judge has not ruled on their request. Suffice it to say, Ben denied any wrongdoing in his only public comments since Andrea McNulty filed suit.
