Britney Spears ex-bodyguard Fernando Flores claims the pop star sent him a series of "filthy" cell phone pictures that will support his sexual harassment suit.

Flores is suing the pop star to the tune of almost $15 million after he filed a suit last year claiming his boss exposed herself to him repeatedly and made unwanted advances.

"They are really explicit images that will shock and disgust the majority of her fans," a friend of Flores' (who says he's seen the pix) tells The Sun.

"Some of the pictures show Britney with the camera between her legs. Others show her in provocative positions wearing lingerie," the source reveals. "There are a few where she is naked, exposing herself in a way that she clearly hoped would make him aroused. Fernando says he can prove the photos were taken on Britney's phone and sent to his."

Flores is hoping to present these sexts in court to support his case. They could cause real damage to Britney's revamped image if released.

Britney denies the allegations and is fighting to have the case argued behind closed doors.
