Haylie Duff's blog comes with great news; the other half of the Duff sisters is pregnant, and it's a girl.

Haylie Duff's blog was updated with news of a baby girl on the way Tuesday, her first with fiancé Matt Rosenberg. In the Real Girl's Kitchen, Duff gushes out the announcement.

"I have always shared everything with ya'll here on Real Girl's Kitchen...You have been with me through dating, falling in love, getting engaged and now the moment that has changed my life forever!

Today we have big, exciting, wonderful, magical, amazing news! Matty and I are expecting a baby girl! Entering this new chapter of our lives and our relationship has been so special. We are so happy and so in love with her already!!! xoxox Matty & Haylie"

Haylie Duff is pregnant; just last June, the Cooking Channel star revealed her wedding plans with Matt, in an interview with People Magazine.

"We want it to be something that everyone has a good time at, and if your feet hurt in your heels ... take them off!"

The newly expecting mom is already an aunt to Luca, her sister Hilary's two-year old son.

Haylie talked to People Magazine about the news, as her rep confirmed it. "Matt and I are so excited to be expecting our first child. We can't wait to start a family of our own."

Her fiancé proposed to her last April Fools Day, which she admits has taken her by surprise.

"As if announcing The Real Girl's Kitchen tv show wasn't enough, Matt just took me by total surprise and proposed...on April Fool's Day of all days! The moment was genuine and sweet (like him!) and I couldn't wait to say yes! We are so excited and happy to share our wonderful news with everyone!"

The couple just celebrated their anniversary last week, in a romantic getaway in Hawaii. Unaware of the bun already in her oven, Hilary posted an Instagram photo captioned "Happy Anniversary to the greatest man I know. I'm lucky to be yours. @mr_sts."
