Hilary Duff has made her post-birth debut!

The star, who welcomed baby Luca Cruz into the world just a week ago, stepped out in West Hollywood on Thursday for the first time since giving birth.

Clad in skintight leopard-print skinny jeans, a blue-violet blouse and towering platform sandals, Duff, 24, was all smiles while making her way to a hair salon, sans her and hubby Mike Comrie's newest bundle of joy.

"4 am...Sleepy eyed. Feeding baby..whew this job is no joke!" Duff, 24, tweeted early that day.
