Teri Polo and Jamie Wollam
Meet the Parents
actress Teri Polo and her drummer boyfriend, Jamie Wollam, are expecting a child, her rep tells PEOPLE exclusively.
"I'm over the moon! It's my favorite role, being a mom," says Polo. "I know we're expecting a girl and I'm very, very excited."
Polo, best known for playing Ben Stiller's fiancée in Parents
and Meet the Fockers
, is seven months pregnant.
This will be the first child for Polo, 38, and Wollam together. They also each have a son from previous marriages: Polo has Griffin, 5, and Wollam has Carter, 9.
This pregnancy has been "easier physically" than the last one, Polo tells PEOPLE. "I vowed from the start [not to eat the first thing in sight] so I'm a lot smaller than I was with the first pregnancy."
Polo and Wollam met in 2004 on the set of a music video for his former band, Avion. She gave Wollam her phone number, he called her the same night – and they've been together since. They live together in a four-bedroom house in Los Angeles with their kids and five dogs.
Up next, the actress stars in the film Two: Thirteen,
in which she plays a detective overseeing a serial killer investigation.
