Hilary Duff is surely one proud mom.

The former Disney actress, 24, happily shared her “proud momma” moment to her Twitter followers when she discovered her son,  Luca, is finally getting some teeth growing! She tweeted:

“Luca is cutting a tooth!!! It’s the cutest/saddest (because it hurts) getting so big my boy!! Gunna have a little toof lol.”

The first-time mom, married to Mike Comrie, will be celebrating her second year hitched this month, and certainly, by far, her baby’s the best gift she can ever ask for. She shares:

“It’s made [our marriage] stronger. Having a baby is a lot of hard work and you really depend on each other for a lot. There is so much love . . . you can’t imagine it until it happens to you and you look at your husband and you’re like, ‘We did this together.’”

Aww, double congrats to you Hilary, then!
