Amy Schumer returns to the stage 14 days after giving birth

(CNN) -- She's back.

Amy Schumer made an impressive (and surprise) return to comedy on Tuesday, performing for a packed crowd at The Comedy Cellar in New York City. Her performance comes just two weeks after she welcomed her first child, baby boy Gene Attell Fischer, with husband Chris Fischer, on May 5.

A fellow comic snapped a photo of Schumer, 37, holding a microphone next to the famed Comedy Cellar sign. She later posted it to Instagram with the caption, "I'm back!"

Schumer appeared healthy after suffering throughout her entire pregnancy from hyperemesis gravidarum, which is severe nausea and vomiting. She was hospitalised multiple times while pregnant to treat the condition.

The good news is Schumer likely already has lots of mummy material -- she recently posted a picture to Instagram of herself pumping breast milk, calling it her "outfit of the day."
