Kailyn Lowry's Reaction To Javi Marroquin Boozing While On Daddy Duty EXPOSED

Kailyn Lowry and Javi Marroquin aren't letting parenthood stop them from letting loose! While the Teen Mom 2 star has been showing off her bikini body in Hawaii with friends, her estranged husband has been boozing the weekend away! RadarOnline.com has exclusively learned how the mother-of-two feels about her ex's behavior while on daddy duty.

Marroquin, who has son Lincoln in his care while his ex is vacationing in Hawaii, has come under fire by fans for drinking while on daddy duty. "So who's gonna drive home? Or you gonna drink and drive?" a user asked, as another bashed, "Grow up! Your kids are gonna see all this one day!"

But Lowry, 24, wasn't as harsh as fans. "She doesn't feel any type of way towards it," a source close to Lowry told RadarOnline.com. "What he does on his time is his business. She knows Lincoln wasn't with him at the tailgate and was being taken care of."

Meanwhile, Lowry has been vacationing in Hawaii with friends. In addition to posting photos of the island's sights, she has been showing off her bikini body in one-piece looks.

As RadarOnline.com readers know, Lowry underwent a body overhaul in January when she got a tummy tuck, Brazilian butt lift and liposuction of her neck.

But Lowry has come under fire as well, as fans have slammed her for leaving her son Isaac, 6, with dad Jo Rivera and Lincoln, 2, with Marroquin.

"How does she deserve a vacation? She doesn't work and has her kids part time," a hater wrote, as Lowry responded, "Really? Cause I go to school full time and I've had my kids by myself for the past 6-7 months."
