Single Lady! Kailyn Lowry Dumps Sons With Ex Javi Marroquin To Go On Girls' Trip

Kailyn Lowry is taking advantage of her estranged husband's return from deployment by going on a getaway without her sons! RadarOnline.com has exclusively learned the Teen Mom 2 star has left her boys with Javi Marroquin while she jets off to Dallas.

"She's going for a baby shower and a bunch of her friends are going with her," a source close to Lowry told RadarOnline.com. "Javi has both boys so he can spend time with them. She's going for a long weekend."

Marroquin, 24, who returned home from a 7-month deployment in early August, is spending more time with Lincoln, 2, and stepson Isaac, 6, after revealing to RadarOnline.com that he has 50/50 custody of Lincoln and sees him "every other week."

But Lowry isn't the only one going on vacation, as Marroquin has a trip to Myrtle Beach planned for next week.

Although Lowry, 24, opted out of bringing her sons on her vacation, Marroquin revealed on Twitter that Lincoln will be joining him for the South Carolina vacation.

While the exes have been co-parenting well, there is still bad blood between them. Marroquin revealed to RadarOnline.com how he plans to write a tell-all book about the demise of his nearly 4-year marriage.

"It's actually a response to Kail's new book coming out," he said of Lowry's upcoming memoir, Hustle & Heart. "Except mine will be the truth and what she actually did that ended the marriage."
