Hilary Duff Pregnant With Second Child

Hilary Duff is pregnant!

On Friday, June 8, 2018, the Lizzie McGuire alum took to Instagram to announce that she's expecting her second child, a baby girl.

"Guess what guys! @matthewkoma and I made a little princess of our own and we couldn't be more excited!!!!!!" the proud mom wrote, captioning a sweet snapshot of herself with boyfriend Matthew Koma

This will be the on-and-off couple's first child together. Duff, 30, is already mom to a 6-year-old son, Luca, whom she shares with ex-husband Mike Comrie

For his part, Koma, 31, shared the same photo, writing, "We made a baby girl! She will be as beautiful and sweet as her mother... @hilaryduff another incredible chapter begins."

Earlier this week, the Younger star opened up about her current relationship while speaking with E! News. "I got a really nice guy. He's so great," she said, adding that he recently won over her mom, as well. "She was like, 'I just love him. I love him so much. He's the best.' I'm like, 'I'm here. I exist, you know? You're always on my side!' She's such a traitor."

The exciting pregnancy news comes just one day after Duff's older sister, Haylie, announced that she and fiancé Matt Rosenberg had welcomed their second child together. 

"She arrived June 5th, and brought all her magic with her! Ryan is the happiest big sister & we are finally a family of 4!" the 33-year-old mom-of-two wrote on Instagram, captioning a sweet pic of the couple's 2-year-old daughter Ryan holding her new little sister. "Meet our littlest one... Lulu Gray Rosenberg!"

Following the baby announcement, Hilary gushed over her niece on social media. Captioning an adorable snapshot of little Lulu, the former child star wrote, "Beautiful LuLu welcome sweet girl 💖 My new niece has arrived! @haylieduff she's perfection."

Congratulations to the happy couple!
