Attractiveness. These two aren't as glamorous as some other couples, but they're positively adorable. Jennifer's just a little too pretty to pull off the girl-next-door look, and even unshaven you can see how handsome Ben is.
Popularity. Last month, around 368,000 people searched Google for details about Jen, and 300,000 searched for Ben. Good news: Those numbers actually put this couple in the top half of our list of most popular couples.
Staying Power. These two have been together since 2004 and married since 2005, and they have two daughters together, Violet and Seraphina. (Watch the video below to hear her tell David Letterman all about her family.) However, both of them have a rich history of Hollywood dating that makes you wonder if they'll move on again. Ben's been linked to Gwyneth Paltrow and Jennifer Lopez, while Jen's gotten serious with two costars. She was previously married to Felicity actor Scott Foley, and she dated fellow Alias star Michael Vartan.
Compatibility. This is about as compatible as two people can be. Jen's a fiery Aries, while Ben's an extroverted Leo, and together the couple is completely focused on one another. But be cautioned: They should think about the excitement that brought them together in addition to their responsibilities so they don't feel too bogged down. Maybe Seraphina and Violet need an occasional babysitter.
