two children together, the duo are engaged to be married.
Richie announced the news using mainstream media, during a taping of The Late Show with David Letterman on Monday night.
Madden took to his Twitter page to ensure that the news went viral. "Yep. i'm engaged. Very happy. Yeah we've been engaged for a while so your all kind of late on that. But Thanks for the hooplah all the same," Madden tweeted Monday night.
He also thanked relatives and friends for keeping the news a secret. "P.s. thats why i love my family and friends. None of them are sources. All good tight lipped people who let us enjoy it! Thanks everybody"
People magazine: "We designed it together. Nicole was lovely and wonderful to work with on it! She wanted a beautiful, special ring and wanted to be intimately involved in the design."
The jeweler to the stars added, "Joel just wanted her to have her dream ring." Isn't that sweet?
Richie, 28, and Madden, 30, began dating in December 2006 and are parents to daughter Harlow, 2, and son Sparrow, 5 months.
Coincidentally, Madden's ex-girlfriend Hilary Duff is also newly engaged. Guess their break-up really was for the best!
