Get to Know the Couples on Big Brother 9

at . Comments

Big Brother 9 is subtitled "Til Death Do You Part." How come?

Because the house guests are playing in teams. With interviews and personality tests, CBS has paired each contestant with their supposed perfect love match. These couples share beds and teams will be evicted at the same time.

With that in mind, here are a couple of the teams vying for this season's Big Brother title:

Allison and Ryan

Meet Allison, 28, a pharmaceutical sales representative from Boston, Massachusetts; and Ryan, 27, a college student from Columbus, Ohio.

Amanda and Alex

Here's Amanda, 23, a paralegal from Fridley, Minnesota; and Alex, 24, a DJ company owner from Staten Island, New York.
