Congratulations are in order for Lizzie McGuire! Or should we say, Hilary Duff.

The Younger star, 30, revealed that she and boyfriend and singer-songwriter Matthew Koma, 31, are pregnant in an Instagram on Friday, just one day after her sister, Hayley Duff, 33, gave birth to her second child, Lulu Rosenberg. To accompany the cute reveal image, Duff wrote, “Guess what guys! @matthewkoma and I made a little princess of our own and we couldn’t be more excited!!!!!!” So indeed, they’re expecting a baby girl.

Duff is already mom to son Luca Comrie, 6, with ex-husband Mike Comrie, 37. Recently, she told InStyle she’s similar to her Younger character Kelsey, though she doesn’t see her having children in an upcoming season. “I don’t think she’s nurturing like I am. I knew I wanted to be a mom at a young age and that would be scary [if she was a mom right away],” she told us in reference to the idea of Kelsey giving birthday.

Last year, she also offered up advice for new moms everywhere, something she’s probably given plenty of to her sister Haley. “I just say enjoy every moment,” she told People. “Hunker down and not put too much pressure on yourself and really enjoy the days as they come. Every baby is different and every style of parenting is different. You’ve gotta just find out what works for you and feel confident with that. It’s such an amazing adventure to go on and such a miracle.”

Wise words.
