OOPS! “The Simple Life” star Nicole Richie managed to pepper Wednesday’s live telecast of the “Billboard Music Awards“ with profanity that Fox’s censors weren’t fast enough to bleep out.

“They call it the simple life? Have you ever tried to get cow-s*** out of a Prada purse?” Richie wondered, in a scripted presentation while sharing the stage with her co-star, hot-blooded hotel heiress Paris Hilton.

“It’s not so f****** simple,” she said, while the audience gasped.

Several of her earlier foul-mouthed phrases were bleeped out.

According to Fox, Richie’s cuss words came out so fast that the digital delay used by network censors to bleep out profanity just couldn’t keep up with her.

“We experienced a failure in the system designed to prevent such an occurrence and are working to ensure that it does not happen again,” Fox officials said in a statement.

“Fox sincerely regrets the error.”
