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
rumors 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."
