WASHINGTON – It took a week, but someone finally noticed Kate Hudson's engagement ring.

It happened on NBC's "Today" show Wednesday when Matt Lauer was starting to interview Hudson about her upcoming movie, "Something Borrowed."

He noticed a huge diamond ring on her finger and she revealed she'd gotten engaged to Matt Bellamy, lead singer of the British rock band Muse, a week ago. She said she was waiting for someone to notice.

No wedding date has been set.

Hudson and Bellamy are expecting their first child. Thirty-two-year-old Hudson said she believes she's having a girl.

Hudson has a 7-year-old son, Ryder, from her marriage to Chris Robinson of the Black Crowes.
