Troubled singer Amy Winehouse reportedly wants a nose job to fix her "witch-like" nose and also wants a doll made in her likeness in a bid to become the next Barbie.

The 'Rehab' singer recently splashed out 35,000 pounds to have her breasts enlarged and is now planning more surgery to improve her appearance, against the wishes of her loved ones, The Sun online reported.

"Everyone tells her there's nothing wrong with her nose. But Amy does nothing by halves. Now she's beaten drugs, plastic surgery must not become her next obsession," a source told the publication.

"Since changing her boobs Amy has been scrutinizing her body," the source added.

The 26-year-old star also wants a doll of her made so she can become the next Barbie.

The Grammy-Award-winning singer has been busy sketching designs for the toy which she believes would be a hit with kids.

"She loves all the compliments and wolf whistles she gets from her new figure. She's been sketching lots of drawings of herself and wants to bring out a doll for fans," the source added.
