Javi Marroquin isn't happy with recent rumors regarding his relationship with step-son Isaac.

Earlier this week, after returning home from his deployment in Qatar, the Teen Mom 2 star was accused of abandoning the 6-year-old, who is the oldest child of Marroquin's soon-to-be ex-wife, Kailyn Lowry.

"Lmao ditching isaac? Who comes up with this stupid s**t? Haha I spent all day with him," Marroquin wrote on Twitter in response to the Radar Online report. "I don't need to explain anything to y'all tho."

On Monday, after arriving to Delaware late on Sunday, Marroquin traveled to Lowry's home where he was greeted by Isaac and his young son, Lincoln, 2. One day later, he was accused of snubbing Isaac.

"When Marroquin returned from Air Force deployment on August 1st, he drove Isaac, 6, and Lincoln, 2, to camp. But while Marroquin brought the children shopping afterwards, it was his son Lincoln who spent the night with him," Radar Online alleged on Tuesday.

"Marroquin even took his youngest son out to breakfast the next day without his older brother," the outlet added.

The outlet went on to reveal that because of Lowry's custody agreement with her ex-boyfriend, Jo Rivera, Marroquin may not be able to see the boy as much as he'd like.

"Since there's a custody agreement with Kail and Jo for Isaac, it depends on what days they decide to have Lincoln with Javi," a source close to Lowry exclusively told RadarOnline.com. "He'll definitely get to visit Javi, but it gets a little more complicated if it works for to be when Jo has Isaac."
