Singer Ashlee Simpson reportedly uses regular collagen injections to help her maintain her youthful looks.

The 23 year old’s father Joe recently confirmed that his daughter had had rhinoplasty to help her breathing and to reshape her nose in April 2006. Ashlee herself refuses to comment on the issue, although has commented in the past that she is not averse to cosmetic surgery.

“I don’t get bothered by people saying what they say,” she said. “I am a happy person and I am happy with my looks – I am not an insecure person. I believe it somebody chooses plastic surgery, it should be for themselves, not for anyone else.”

A source close to Simpson has revealed that the star visits her plastic surgeon once a month to have fillers injected into her face. These fillers help to get rid of any wrinkles that are starting to appear, and help her face remain young, taut and smooth.
