Hilary Duff is introducing her baby to the world!

The pregnant star, 36, revealed her baby’s “cute" standout feature in a sonogram posted on Friday, after sharing the news that she is expecting her fourth child earlier this week.

“Little stinker with the cute nose,” Duff wrote in the caption over her Instagram Story post, which included the sonogram image showing her new baby's adorable nose in the center of the shot.

Duff announced that she is pregnant with her fourth child — and third with her husband Matthew Koma — on Instagram Tuesday when she posted her family Christmas card on the social media platform.

The front of the card displayed a photo of Duff with her hand on her baby bump as she posed in pajamas with husband Koma, 36, their children Banks Violet, 5, and Mae James, 2, and her eldest son Luca Cruz, 11, who she shares with ex-husband Mike Comrie.

“Surprise, surprise,” Duff wrote in the caption at the time.

"Baby #4 is loading…," Koma also wrote on Instagram as he posted the same family photo.

"So much for silent nights," the Christmas card read. "Love, the Duff-Bair-Comrie Crew." The back of the card showed more photos of Duff’s kids as a second message read, "Buckle up Buttercups, we're adding one more to this crazy bunch!"
