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 Thursday for the first time since going into labor.

Clad in skin-tight 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.

Early Tuesday morning, the new mom took to Twitter to reveal her newfound respect for motherhood.

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

"Luca fed! Mamma fed! Time to do it all again in 2 hours! Oh how life has changed! Lol In such a wonderful way :)" she posted the day before.
