(Cover) - EN Showbiz - Michelle Williams says being a mother is an "incredible experience".

The Hollywood actress is mom to six-year-old Matilda, her daughter with late actor Heath Ledger. Michelle is proud of her youngster, and says motherhood has completely changed her for the better.

"It's wonderful. I love spending as much time as I can with Matilda and watching her grow and become such a beautiful, sweet little girl," she gushed in an interview with the UK version of OK! magazine.

"It's an incredible experience and it's totally transformed me as a woman."

Michelle says Matilda has allowed her to enjoy life again. The stunning star has learnt to be happy since the tragic passing of Heath in January 2008.

"I think so," she admitted when asked if this is a good time in her life.

"It's taken me a while to feel really good again and to think more freely and just be myself. I have so much joy in looking after Matilda that I don't even worry that much about myself anyway. There's a lot to be said for just going about things, working on good films, making lunches and going shopping with your child." (C) Cover Media
