The woman behind The House of Harlow 1960, Nicole Richie, and long-time boyfriend Joel Madden are said to be engaged.
Richie confirmed the rumor on an episode of David Letterman (February 15), by which Madden replied via Twitter, "Yeah we’ve been engaged for a while so your all kind of late on that. But Thanks for the hooplah all the same."**
The couple have dated since late 2006, according to People.com, and are the proud parents of daughter Harlow Winter (2) and son Sparrow James (5 months).
