Britney Spears slapped with allegations of bad hygiene

Maybe they should call her the “slop tart.”

In his sexual harassment suit against Britney Spears, a former bodyguard claims the singer refuses to shower, chronically picks her nose and passes gas “unapologetically,” according to court documents.

Fernando Flores is seeking a $10 million in damages from the pop princess, who’s on tour in support of her latest hit album, “Femme Fatale.”

Spears was “mentally unstable, and personally obnoxious and demanding, requiring her staff on various occasions and for no rationally discernable reasons to address her as ‘Jennifer’ or ‘Queen Bee,’” Flores alleges, according to RadarOnline.com and Star magazine.

“On other occasions … Spears would cut her hair in an erratic fashion, leaving uneven and bald spots on her head,” Radar reported.

Flores, 29, says he worked for Spears for six months last year, and was subjected to her come-ons and attempts to expose her “naked or near naked body.” The final straw was after she allegedly tried to flash him in a short nightie in her Calabasas, Calif., pad in July 2010.

Flores also alleges Spears was hooked on a cocktail of prescription drugs, chain smoked and cussed, ultimately causing him psychological distress.

TMZ.com said Wednesday that Spears is calling him out as a “liar.”

A rep for Spears didn’t return a request for comment, but Radar said her lawyers are trying to get the suit thrown out, claiming he’s continuing “to embellish on his tale of lewd and sensational allegations.”
