Hilary Duff Pregnant

On Sunday, Hilary Duff and her hockey-player hubby, Mike Comrie, celebrated their one-year wedding anniversary. But they had even bigger news for their fans over the weekend. Duff announced on her official website that they are expecting their first child.

"Hello everyone! This weekend, Mike and I are celebrating our 1 year anniversary! In memory of the special day, we decided to post some of our favorite pictures from our wedding!" the 23-year-old 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!!!"

She added, "We are extremely happy and ready to start this new chapter of our lives. Thanks to everyone for the continued love and support throughout the years! Wow! I am just overwhelmed by all of the wonderful messages everyone is sending! Thank you so much! Big hugs! Xxo"

Duff, who rose to fame on the Disney Channel playing Lizzie McGuire, has gone on to become a Hollywood mogul. She met the Edmonton Oilers star in 2009. "[Comrie's] a great guy. I've never met anyone who could say a bad word about him. He's generous, caring, funny. We just laugh our heads off, which I need in my life," Duff has said of her husband. "He's unique. I wouldn't want to be with someone who wasn't unique."

Days before she officially announced she was expecting, she spoke to Usmagazine.com about having kids with Comrie, telling the website, "We both love kids and we're really excited. It was a big deal for us because we had a year to be married."
