The 33-year-old actress - who has a five-year-old daughter Ramona with her husband Peter Sarsgaard - is said to be expecting the couple`s second child next year.

A friend told Life & Style magazine: "Maggie has been telling friends that she`s six months pregnant. Her bump is so big!

"She`s thrilled to be pregnant! She and Peter have wanted another child for a while. They`re very happy that they`ll have another baby in the house soon."

While Maggie and Peter are thrilled with their news, her brother, `Brokeback Mountain` star Jake, is also delighted at the announcement that he is to become an uncle again.

The source added: "Jake is so happy that she`s pregnant again because he loves kids. Maggie`s said that he`s the best uncle and has done a lot of sweet things for her first child."

Maggie and Peter - who live in New York with Ramona - have been in a relationship since 2002 but only married in 2009 after their daughter was born.
