The Real Girls Kitchen host is expecting her first child, a daughter, with fiancé Matt Rosenberg, her rep confirms to PEOPLE.

“Matt and I are so excited to be expecting our first child. We can’t wait to start a family of our own,” the mom-to-be tells PEOPLE.

“Today we have big, exciting, wonderful, magical, amazing news!” Duff wrote on her blog, The Real Girl’s Kitchen.

“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!!!”

Duff, 29, and Rosenberg got engaged in the spring, when the T-shirt entrepreneur popped the question on April Fool’s Day.

“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 Cooking Channel star told PEOPLE of her wedding plans in June.

The mom-t0-be is already an aunt to Luca Cruz, sister Hilary Duff‘s 2-year-old son.
