Martha Stewart and Bridget Moynahan

It's tough to impress Martha Stewart – but pregnant actress Bridget Moynahan did just that.
"Now wouldn't you like to look like that?" Stewart asked her studio audience while taping an interview with Moynahan set to air on Monday. "What month are you in?"
"This week [it'll be] five months," said the Six Degrees
actress, 35, who announced in February
that she's expecting her first child with her ex-boyfriend, New England Patriots quarterback Tom Brady.
"Five months pregnant!" Stewart said. "Are you excited about being a mom?"
"I am. I'm a little nervous, 'cause I haven't done it before," said Moynahan. "But, you know, I have little nephews, and it's always nice to spend time with them, especially around the holidays."
Brady and Moynahan split late last year
after three years together, but a spokesperson for the football star said last month: "Tom and his family are excited about the pregnancy."
And a friend of Moynahan's told PEOPLE that the actress is "so excited about the pregnancy – she knows she'll be a great mom."
