Nicole Richie and Joel Madden: Engaged!

Nicole Richie and Joel Madden, who have been together for several years and are already the parents of two adorable children, are getting married.

Richie made the announcement Monday night on The Late Show. Madden followed it up with a confirmation Tweet: "Yep. i'm engaged. Very happy."

Sums it all up right there. He adds: "Yeah we've been engaged for a while so your all kind of late on that. But Thanks for the hooplah all the same."

A source tells Us Weekly of the pair: "Nicole and Joel are in the process of planning the wedding. She's very involved in every detail. She’s thrilled."

The couple is expected to marry (for real this time) in the summer.

Richie and Madden started dating all the way back in December 2006 and have two children together: daughter Harlow, 2, and son Sparrow, five months.

"For us, we are going to do it because we want to," said Richie last year of tying the knot on her own time. "We're going to do it when the time's right."

Looks like that time is now.

These two have been a nice, relatively normal couple and cute family for so long, but it's great to see they are making it official. Congrats Nicole and Joel!
