The `Rehab` singer - who recently splashed out thousands of pounds on a breast enlargement operation - is thrilled with her new "womanly" appearance and wants to go under the knife again to boost her assets even further.

A source said: "Amy loves her breasts. She can`t stop touching them and showing them off to friends. She says she feels womanly again and wants to be more curvy like she used to be. She thinks by having another operation and bum implants that she will achieve her dream pin-up look."

When Amy first burst onto the music scene in 2003 with her debut album `Frank` she was known for her curvaceous figure.

However, as she battled alcohol and drug addictions over the years her weight plummeted.

Amy?s father Mitch recently admitted his daughter - who has been drug-free for a year - was forced to undergo surgery because she was left with "saggy" breasts.

But the slim starlet is reportedly gorging on 3,000 calories a day to add curves to the rest of her frame.

An insider said: "Amy`s like a machine at the moment. She just can`t stop eating. She loves T-bone steaks and fish covered in oily sauces. She has set a target to eat up to 3,000 calories a day while also doing work in the gym."

The 26-year-old star is so serious about getting her old figure back, she has even had fitness equipment installed into her home and spends most of her spare time there.

Mitch said recently: "One of Amy`s positive addictions is she`s got her own gym. She`s in the gym three or four hours a day. I mean boy is she fit - really, really fit. So that`s a really positive addiction."
