The actress, 32, and her fiancé, Muse frontman Matthew Bellamy, welcomed a "healthy baby boy" on Saturday in Los Angeles, Hudson's rep tells PEOPLE.
In January, Hudson announced that she and Bellamy, 33, were expecting a baby, and the couple got engaged in April after dating for about a year.
Hudson didn't want to know the sex of her unborn baby, but had a feeling it was a girl.
The actress has a 7½-year-old son, Ryder Russell, with her ex-husband, Black Crowes frontman Chris Robinson. This is Bellamy's first child.
