'Teen Mom' Catelynn Lowell Pregnant Again, Keeping Baby?

Catelynn Lowell and fiancé Tyler Baltierra are expecting their second child and are planning to keep this baby, reports state. The couple previously gave up their first baby, which was featured on MTV's hit series "Teen Mom."

The latest issue of "In Touch" magazine proudly displays a picture of the two stars with the headline "I'm Pregnant!" The news comes the day after the season premiere of the reality show, which is ending its 4-year run this summer.

"This time, [Catelynn] knew immediately that she wanted to keep the baby. She's just so happy," a source told "In Touch." Catelynn is reportedly due this winter and is hoping for another little girl.

Lowell and Baliterra, now 20, were only 16 when they had their first daughter, Carly, and gave her up for adoption.

"We chose adoption with one person in mind, our daughter, because she deserves the best and at the time I couldn't provide her the best," Baltierra wrote on the couple's website. "As a parent, I made the greatest sacrifice in order to provide her with the best life."

Using a Christian adoption center, they have remained in close contact with Carly's adoptive parents and viewers were able to watch their second-year visit with Carly during last night's episode. Lowell and Baltierra have graduated high school and are currently enrolled in college, hoping to become counselors who help teens with the adoption process.

"Teen Mom" has been heavily criticized for "glamorizing" teen motherhood, though the majority of its stars have refuted the claims, saying that they struggle and are normal, everyday people. Lowell and Baltierra are one of a few couples to choose adoption for their child, which has led to them becoming stars in their own right and speaking about their decision to put Carly up for adoption.
