ET has the latest...

ET confirms that singer and BLACK EYED PEAS frontwoman FERGIE, 32, and "Las Vegas" actor JOSH DUHAMEL, 35, are engaged. No wedding date has been announced.

The two met three years ago when Miss Fergalicious guest-starred on the set of Josh's NBC show, "Las Vegas," and he got "clumsy" and used the oh-so-clever opening line, "You're so hot!"

At November's "American Music Awards," the glamorous singer got emotional while accepting the award for "Fave Pop/Rock Female" and, while tearing up, thanked her family at home, and "my man who's here supporting me," boyfriend Josh, whose eyes were shining back from the audience!
