Kate Hudson is pregnant

Kate Hudson is expecting a baby with her British rocker boyfriend Matt Bellamy, according to a U.S. report.

The 31-year-old actress has been dating the Muse front man since last summer and the couple is now reportedly about to become parents, according to Us Weekly.

Hudson, who has a son Ryder with her ex-husband Black Crowes front man Chris Robinson, is said to be three months pregnant.

A source tells the publication, "It was not planned, but they are excited and embracing it. She is happy for Ryder to finally have a brother or sister."

The daughter of Goldie Hawn has two films due for release later this year.

In an interview in 2007, Hudson talked about the effect that motherhood had, had on her life. “You realise after you have had children that you'll never love anything more than your child,” she said.
