After three years and two children together, Nicole Richie and Joel Madden finally let the world know something their friends and loved ones have been privy to for awhile: they're getting hitched!

Richie was the first to pop the cork on the news, confirming the news during her Monday taped-appearance on 'The Late Show with David Letterman.'

Shortly after, Good Charlotte front man Madden had his say, taking to his Twitter page to add his own twist on the announcement. He revealed that the two have actually secretly been engaged for some time.

"Yep. I'm engaged. Very happy," Madden wrote. "Yeah we've been engaged for a while so you're all kind of late on that. But thanks for the hooplah all the same."
