Ashlee Simpson and Pete Wentz are getting married!

Simpson, 23, and Wentz, 28, the bassist for Fall Out Boy, have been a couple since the fall of 2006, when they meet at a New York nightclub and now have decided to tie the knot.

"We know there has been a lot of speculation recently about Pete and I, and we wanted our fans to be the first to know, because you guys are the best," Simpson said in a statement posted on friendsorenemies.com. "Yes, we are thrilled to share that we are happily engaged. Thank you for all of your support and well wishes - it means the world to us. We consider this to be a very private matter, and we wanted to be the first to tell you and to hear it straight from us."

"I think the first day that we met that we were attracted to each other," Simpson recently told PEOPLE.

Because they were with other people, "Neither one of us did anything," said Wentz. "That was good." But they quickly became friends, even as Wentz found that "I was into everything about her." Simpson felt the same way.

"He's a cutie," said Simpson, "and he has an awesome personality and kind of brings out the best of me and I knew that even before we were dating. There was just like an awesome connection we had."

Good luck to the couple and all the best for their future together!
