“Mad Men” star Elisabeth Moss announced on “Jimmy Kimmel Live” on Tuesday that she is pregnant with her first child.

The 41-year-old star was all smiles as he revealed the exciting news on the late night talk show. Kimmel introduced Moss on stage and immediately addressed the topic.

“Are you pregnant or are you an incredibly dedicated method actor?” Kimmel asked, referring to his current role in “The Handmaid's Tale.”

“A little bit of both,” Starr replied.

Moss told Kimmel that she has been “really lucky” with her pregnancy thus far.

“It's going great,” she said, asking Kimmel for advice about pregnancy, the delivery room and “anything” he could offer insight into.

Kimmel jumped right in when she let Moss know that friends and loved ones would be buying her lots of baby supplies, and the famous actress seemed thrilled to hear about the generous gifts.

The comedian then shared the valuable advice he received from Bill Murray when his wife Molly McNerney became pregnant with one of their four children.

“He said, 'Bring me some Christmas lights so I can hang up.' [in the delivery room]'' Kimmel said. “Because the lighting in the room is terrible. It's Walmart-style lighting for this blessed event that's about to happen, and that's not what I want.”
