'Teen Mom 2' Star Kailyn Lowry Pregnant, Rushed to Hospital

"Teen Mom 2" star Kailyn Lowry, who is pregnant with her second child, was rushed to the hospital on Saturday night. Husband Javi Marroquin was with her the entire time, and now Lowry is home and doing well.

"The beach yesterday was definitely worth my trip to the ER last night from dehydration afterwards," Lowry tweeted. "I'll just drink water all day next time."

The 21-year-old spent the day at the beach with son Isaac and Marroquin, enjoying some rare family time. Marroquin recently left the Air Force after fulfilling his contract, and the couple has been busy filming for the upcoming season of "Teen Mom 2."

"Yeah, I was throwing up all night. It was awful! But a lot better now! It was good seeing you!" Lowry tweeted later on, assuring fans that all was well.

It was a scare for fans of the series, who remember when Jenelle Evans was rushed to the hospital at times for ovarian cysts, but then for a miscarriage. Evans lost the child she was expecting with husband Courtland Rogers. Eventually the couple separated, and Evans is now focused on regaining custody of her son Jace, who lives with her mother.

Lowry has had a completely different experience. She was with Isaac's father, Jo, for a long time before they separated. She dated off-and-on but settled down with Marroquin. When it came time for him to enroll in the Air Force, he proposed to Lowry so that she and Isaac could live with him wherever he was sent.

It wasn't long after they wed at the courthouse that Lowry became pregnant with their first child. Neither Lowry nor Marroquin has spoken much about the pregnancy, but family members say that they are both ecstatic and eager to welcome a little one into the family.

The new season of "Teen Mom 2" is being filmed now and should air late this year or early next year.
