Kailyn Lowry is stuck between the fathers of her two children in a new sneak peek for the upcoming season of MTV's hit reality TV series "Teen Mom 2." The mom spent last season facing off with both her ex-boyfriend Jo Rivera and her husband Javi Marroquin, and a clip from the upcoming new season suggests that things haven't changed.

In a sneak peek for the season premiere of "Teen Mom 2," a sweet moment at a family photo shoot turns sour when Lowry attempts to convince her husband to attend a family dinner with her ex, his pregnant girlfriend Vee Torres and their sons.

Lowry meets up with Rivera and Torres at a local park so they can be a part of the photo shoot she set up for her 6-year-old son Isaac (whom she shares with Rivera) and her 2-year-old son Lincoln (whom she shares with her Airman hubby Marroquin). Lowry suggests they all go out for dinner and, once she's settled in the car with the kids, she calls Marroquin to try to convince him to join them.

The phone rings through the car's speaker. When he answers, she says, "Isaac wants to talk to you."

"Dad?" Isaac asks. "I want you to... I want to invite you to come and eat dinner with us."

"I know, dude," Marroquin responds. "But my body hurts."

"What if we come pick you up?" Lowry chimes in.

"No, Kail, I just want to be at home," he says, sounding frustrated. "Like, I spent all day, we're constantly on the move. I just want to be at home. I would appreciate it if you dropped off Lincoln so I can hang out with one of my kids at least."

Lowry protests because she doesn't want to drive out of the way to drop off her youngest son and then she argues back-and-forth with her husband. He demands that she bring Lincoln home because he wants to spend time with him, but Lowry doesn't believe him.

"No, you don't want him to go to dinner with us all, that's what you don't want," she hits back.

"Well, first of all, if I'm not there, there's no reason for Lincoln to be there," he says stubbornly.

She tries to end the argument by hanging up the phone, and cuts her husband off.

"No, don't start this," he says as she disconnects the call.
