Natasha Hamilton has undergone cosmetic surgery to make her feel less ''subconscious'' about her body.

The Atomic Kitten star - who has Josh, 13, Harry, 11, Alfie, six, and 21-month-old Ella - has struggled to feel confident in her body and has opted to get ''Botox and fillers'' in her face as well as a boob job and laser treatments on her breasts.

She explained: ''I've had Botox in my frown lines on my forehead and I've had some filler in my top lip. I do get comments about my cheeks, but I've not had anything done and I haven't touched my bottom lip. When I was younger it didn't interest me, but I've spent a long time thinking about it and now I'm at an age where I feel it'll help - and I want to feel good about myself''

Although the 33-year-old redhead has said she won't take it too far when it comes to cosmetic surgery, she would be open to more procedures.

She added: ''I'd never say never to more surgery but I don't have anything planned. I've done a lot of research into fillers and Botox and there are so many disaster stories out there. You do have to be careful.''

And Natasha has also felt the need to have laser treatment to remove the stretchmarks that came with her pregnancies.

She told Closer magazine: ''I breastfed three of my kids and, when I stopped, I had deep purple lines around my breasts, especially after Ella, my fourth child. It used to make me feel self-conscious but I had an hour-long session of laser treatment in January and gradually after six weeks the marks disappeared. It was a massive boost.''
