The 'Boyfriend' singer is fed up with rumours she has had plastic surgery to enhance her cleavage and says her boobs are perfect as they are.
She told Britain's OK! magazine: "You have to laugh because people make up the goofiest things. My boobs are beautiful! I'm not getting them done. I'm 22, they're up and high." However, the singer - who is currently starring in West End production of 'Chicago' - admits she gives her cleavage a boost when she plays seductive Roxie Hart.
She said: "I have pads in my dress that you can knock on - it's like four Wonderbras." Ashlee confesses her hectic career is ruining her love life.
She explained: "I'm young and I just love working. When I'm not working, I'm wishing that I was." Meanwhile, Ashlee's older sister, 'Dukes of Hazzard' beauty Jessica Simpson has confessed she loves phone sex.
She said: "I definitely have fun with late-night phone conversations but I'm keeping that private."
