Kate Hudson is officially engaged to her unborn baby's father, Muse rocker Matthew Bellamy.
In an interview on The Today Show Wednesday, an observant Matt Lauer happened to notice Hudson sporting a giant diamond ring and asked her about it.
"I haven't really announced it, I was waiting for someone to notice," she said, confirming the engagement. "He's a beautiful man and I'm very excited."
Hudson has one son with her ex-husband, Black Crowes crooner Chris Robinson. The Almost Famous beauty, who is Goldie Hawn's daughter, had previous romances with baseball player Alex Rodriguez, cyclist Lance Armstrong and actor Owen Wilson.
