Success. Ashlee's had two number one albums, Autobiography and I Am Me, which sold around 620,000 combined in their first weeks. Last year's Bittersweet World was far less successful, considered a commercial flop. As for Wentz, Fall Out Boy's 2005 album From Under the Cork Tree won several MTV and Teen Choice Awards and sold more than 2.5 million albums in the US alone. Not bad, but that was four years ago, and both of these kids' careers seem to have cooled off a little since then.
Attractiveness. Ashlee has always been cute, but she gained more mainstream attention for her good looks after her nose job in 2006. And it doesn't help that she grew up in the shadow of her bombshell big sister, Jessica Simpson. For his part, Pete is pretty average-looking and relies on eyeliner and hoodies for his signature edge.
Popularity. Last month, about 673,000 people searched Google for details about Ashlee and 368,000 for Pete, pushing them into the top half of our most popular couples list.

Still, they're fairly young -- Ashlee is 24, and Pete's 29 -- so anything could happen. Watch the video below to hear how they've bonded over seeing each other naked and a mutual love of makeup.
Compatibility. Since Ashlee's a Libra and Pete is a Gemini, these two make a great team. They're well-rounded with a wide range of interests, so they won't get bored with each other either, and they'll probably inspire each other's creative pursuits. Raise your hand if you want to see Pete on Melrose Place, too.
