From her first appearance on MTV's 16 & Pregnant, Catelynn Lowell's story has been a bit different from the rest of the cast. Not only was she was the sole teen to give her baby up for adoption, she's also the only one who has remained with her boyfriend of the time, Tyler. While Catelynn calls Tyler her soulmate, she says not to expect wedding bells any time soon. "We're too young!" she says. TVGuide.com caught up with the 19-year-old about her relationship with Tyler, how she's handling the decision to give up Carly and which fellow Teen Mom cast member she's closest with.
