Looks like another teen mom is adding to her brood.

Kailyn Lowry, who appears on "Teen Mom 2," is pregnant once again … and not with the same father of her 3-year-old son Isaac.

The 21-year-old dental assistant is expecting a second child with her husband of six months, Javi Marroquin, according to In Touch. "They're overjoyed," his sister, Lidia Marroquin, tells the magazine. "When Kailyn told Javi, he cried."

It's unclear how far along Lowry is or when she's due, but another source tells In Touch that she and her new husband conceived over his winter break from the Air Force. Although they did want a child together eventually, "they weren't preventing it either," explains a friend. "They're nervous about the transition to two children, but are so excited!"

The timing may not be the best, since there's a chance that Marroqouin could be deployed overseas in the coming months, but luckily his family lives nearby, "and we're all happy to help her," says his sister Lidia.

Lowry is not the first cast member of "Teen Mom 2" to add to her family. Mom-of-twins Leah Calvert gave birth last month to her third child, her first with her second husband. And of course, the eternally troubled Jenelle Evans – who does not even have custody of her son Jace – recently miscarried after allegedly being physically abused by her husband.

Lowry did not immediately respond to omg!'s request for comment on her reported pregnancy.
