Britney Spears is thinking about a new look

Britney Spears is thinking about a new look OK reports.

“She's always worrying about what she looks like,� one friend of the Toxic singer reveals to OK!.

“She checks pictures of herself on the Internet every night and criticizes every single one."

Spears plans a little bit of nipping here and tucking there, says the friend. She already underwent lip enhancement and forehead Botox on Oct. 18, a decision which the friend says was "spur of the moment."

On her checklist: liposuction of the abdomen, hips and thighs ($18,000); a breast lift with change of silicone implants ($25,000); a mini tummy tuck ($18,000); and work on her nose ($20,000).
