May 18, 2008 -- JANICE Dickinson just can't keep her opinions to herself. The mouthy mannequin tells Page Six she has a bone to pick with Tyra Banks, that Kevin Federline is a "pig," and thatSimon Cowell is the hottest guy in Hollywood.

Dickinson told us she recently "flipped out" when she saw a paparazzi photo of Banks in a magazine carrying a copy of Dickinson's book, "No Lifeguard on Duty," in which she writes about sex, drug use, incest, celebrity affairs and her near-fatal car wreck some years back.

Dickinson showed us the torn-out magazine photo with a caption saying Banks was on her way to speak with young girls and offer her advice.

"And she's using my book," Dickinson fumed. "I mean, the thing looks so worn it's like she's been reading it on the toilet. It's pathetic. Where's her originality? Does she have no shame?" Dickinson, who's in talks with NBC for her own chat show, said she'll invite Banks on to confront her.

Next, she said Federline "makes me sick. His earlobes are stretched out from all the diamonds he stole from Britney Spears. He's a pig and a loser and I want to take him down."

On Dickinson's good side is "American Idol" judge Cowell - "the hottest thing on TV. The guy's a-- is finally not hanging off the back of his kneecaps," she said of the new, leaner Cowell.

Dickinson, 53, also dished to us about her menopause. "I'm taking hormone pills and I mix them up, I'm like falling asleep standing up," she laughed. "I'm having night flashes and heat strokes."

She's dating " 'Soprano' wannabe" Joe Kaplan, will soon be in Los Angeles taping the fourth season of "The Janice Dickinson Modeling Agency" for Oxygen, and is also working on a new book to be titled "Fifty and Fabulous."
