In the upcoming summer film, Away We Go
, Maya Rudolph's character is pregnant. Well, off-screen, the actress is pregnant too!
The Saturday Night Live
star, 36, is expecting her second child with her partner, director Paul Thomas Anderson, she reveals in an interview slated to air Monday on ET Canada
"I wasn't planning on sharing it, but yes I am pregnant!" she tells the show. In a nod to the irony of playing pregnant, followed by actually being
pregnant, she says, "I know it's really weird timing."
Already mom to daughter Pearl, 3, Rudolph says her current pregnancy is "totally different" than her first one. "The first time you are like wide-eyed: 'What are we doing?, Who's coming?, How do we take care of them?' But this time, I'm like I have to sit down, I'm pregnant.' "
She adds, "When you have a three-and-a-half-year-old, you don't have time to rest and nap and do all the those sweet pampering type things you did for yourself the first time. You are like, 'I got to get to bed!'"
As for adding to her family, Rudolph says she's psyched. "I feel like everyone who has had more then one [child], says you should do it. It's nice to have this experience."
