Ashlee Simpson before (L) and after (R) her nose job.
Ashlee Simpson's father has confirmed she has had a nose job, but claims it was because she had trouble breathing.
Joe Simpson, who manages her singing career, says the 22-year-old star underwent rhinoplasty last year purely for health reasons.
Joe - who also manages eldest daughter Jessica -
told Us Weekly magazine: "Girls have their own ideas. Anyway, there was a real problem with her breathing and that was cured."
It was recently claimed Ashlee - who has always refused to comment on rumours she had plastic surgery - decided to have her nose straightened so she could be as attractive as Jessica.
A source said: "Ashlee has always been cute but for a long time she felt like the ugly duckling of the family compared to Jessica. Every time she looked in the mirror, she saw a too-prominent nose, and she decided to do something about it.
"She was thrilled with the results. She basically had the bump on her nose shaved down."
Meanwhile, Joe claims he played no part in the breakdown of Jessica's marriage to Nick Lachey.
The former Baptist minister denied claims he is a controlling father who runs his daughters' love lives.
He said: "I don't tell my girls who to date or marry or what to do.
"I have nothing against Nick. But they got married very young. I told Jessica, 'You're going to hit an age when it's all going to be clear to you - life that is - and you'll know what you want to do.' "
