"I'm engaged!" UsMagazine.com said Hudson, who is pregnant with Bellamy's child, told "Today" interviewer Matt Lauer.
"It just happened a week ago. I'm so glad you noticed [my ring]. I haven't really announced it. -- I was waiting for someone to notice."
UsMagazine.com said the "Almost Famous" and "Something Borrowed" star was tight-lipped about how Bellamy proposed to her, other than to say: "It was very sweet. It was very romantic."
The couple have been dating for about a year.
