Kate Hudson is a mom for the second time! The actress gave birth to a baby boy Saturday night, Us Weekly confirms.

The "health baby boy," whose name has not yet been released, was born in Los Angeles to Hudson and Muse rocker Matthew Bellamy.

The new addition joins big brother, Ryder, 7, whose dad is Hudson's ex-husband Chris Robinson.

Hudson, who announced her engagement to Bellamy in April, recently celebrated her expanding family at a baby shower in June.

Hudson had revealed that she was not going to find out the sex of her new baby before the birth, adding she used a "pendulum test" to predict that she'd have a baby girl.
