Kailyn Lowry's Son Hospitalized – Inside His Scary Medical Crisis

Kailyn Lowry's divorce from estranged husband Javi Marroquin is the least of her worries. The Teen Mom 2 star's 6-year-old son Isaac was admitted to the hospital on Sunday, July 10 – and RadarOnline.com has all the details on his medical crisis.

After a trip to the movies, Lowry revealed over Twitter that her son has a fever. She then posted photos on SnapChat of her oldest child in a hospital bed.

"He had a really high fever so Kail just wanted to get it checked out rather than wait for the doctor to be open today," a source close to Lowry exclusively told RadarOnline.com. "He's home and fine now."

Since announcing her split from Marroquin in May, Lowry has been a single mother to Isaac, her son with ex-boyfriend Jo Rivera, and Lincoln, her youngest child with Marroquin.

"Single mom doing whatever it takes," Lowry's Instagram bio now reads.

But she hasn't been alone, as she reunited with rumored girlfriend Becky Hayter on the 4th of July after locking lips with her soon after her divorce announcement.

"I want you to know, I really adore you," Hayter wrote after the holiday. "I should be your girlfriend."

Lowry retweeted her post, "She's gonna steal my heart there's no doubt about it."
