Actress Evan Rachel Wood has addressed her pregnancy in public for the first time, insisting she's always wanted to be a mother.

The True Blood star is expecting her first child with her British actor husband Jamie Bell, and now the usually-private actress has gushed about her impending parenthood.

She tells U.S. news show Access Hollywood, "I'm over the moon. Motherhood is my dream and my husband is always the one I wanted to do it with. I'm very happy!"

The baby news came as a surprise to fans after Wood had previously shut down rumours of a pregnancy just a month before making her official announcement in January (13).

Wood and Bell wed in October (12).
