While most brides worry about their vows on their wedding day, Kailyn Lowry was worried she'd give birth.
"I'm just glad I didn't go into labor," the expecting "Teen Mom 2" star says of her September 21 wedding to Javi Marroquin, which was held at the Adventure Aquarium in Camden, NJ.
In just-released photos from the big day, the 21-year-old bride is seen holding onto her growing baby bump in a white mermaid gown, perfect for the aquatic affair.
Lowry already has one child, son Isaac, with an ex -- and she tells In Touch her vows "talked about how if Javi wanted to be with me, he had to be with Isaac."
The couple has actually been legally married since last September, holding a small civil ceremony before Javi entered the Air Force. They're expecting their first child together in November.
