Actress Hilary Duff has announced that she is pregnant with her first child.

The former Disney star celebrated her first wedding anniversary to hockey player Mike Comrie by announcing the happy news on her website.

Twenty-three-year-old Hilary, who recently appeared in US show Gossip Girl, wrote:

"I can't believe it has already been a year, time really flies when you're having fun!

"We also want to share the exciting news that... Baby Makes Three!!! We are extremely happy and ready to start this new chapter of our lives."

She added that she was "excited" at the prospect of starting a family, despite previous protestations that she wasn't ready to have children.

Duff married Comrie, 30, in a private ceremony in Santa Barbara last August, after a five month engagement.

The pair started dating in 2007.
