Anne Dudek and husband Matt Heller are expecting their second baby together.

Dudek (aka Amber from House) tweeted the happy news to her fans, “18 and a half weeks pregnant and I think my nausea is finally gone!”

Dudek also blogged about how her 2 1/2 year old son Akiva is excited to have a new baby in the family, “Akiva has had a thing for baby girls and even before we told him I am pregnant, he acted as if he had a baby sister. He would play with some toys and lay some aside “for my sister”. I thought maybe it was an imaginary friend kind of thing, but then he started referring to to the baby in my belly as his sister. I tried to tell him it could be a baby brother once but he sort of looked at me like I was crazy.”

The baby (whose gender is still unknown) will be the second baby for the couple and joins big brother Akiva.

Congratulations to the growing family!
