Baby Luca is no stranger on Hilary Duff's Twitter, but he finally made his first public debut Saturday!

Duff and her husband Mike Comrie stepped out for the first time with their son since he was born on March 20. The new parents brought Luca Cruz for a visit to a friend's house in West Hollywood.

Comrie did the heavy lifting for his wife by carrying Luca in his car seat, which the couple kept covered with a blanket. Duff, 24, flaunted her post-baby bod in tight, neon pink jeans.

The new mom has been working out since giving birth with her sister Haylie. Haylie tweeted last Tuesday, "Awesome soul cycle class" and Duff tweeted back, "I agree thanks Soul Cycle."

The proud mother has also been tweeting photos of her adorable son to her 1 million followers. "Babies smell so good!" she tweeted May 12. "I can't get enough. Poor guy gets loved on so much.... I wonder if he ever feels like yo mom, dad give me some space!"
