Ashlee SimpsonAshlee SimpsonAshlee Simpson's plastic surgery rumours raised eyebrows a while back.

But now her real secret is out the bag.

Her perfect brow secret, that is.

Us Weekly says that while her dad, Joe, recently spoke about Ashlee's nose, her spokesperson has had a word about Botox rumours.

Her spokesperson told Access Hollywood: "Ashlee has never had Botox in her life.

"She credits her eyebrows to her make-up artist who is a whiz with the tweezers."

Ash also departed some of her other beauty titbits to Us at the Hollywood Style Awards, saying: "I cheap out and use face wipes to take my make-up off and put lotion on."

To zap zits she says she's a fan of the product, Proactiv: "I know it's very cheesy to say, but the stuff is incredible.

"If I have a zit I put that mask on and it's gone."
