Kailyn Lowry is not happy to see that her Teen Mom 2 co-star, Briana DeJesus, leaked text messages sent between her and her ex-husband, Javi Marroquin, on Twitter.

Shortly after DeJesus shared a screenshot of the messages and quickly deleted it, a source claims that Lowry, who shares a three-year-old son with Lincoln, is upset to see that DeJesus has acted so ignorantly towards her.

“She feels really bad that she’s so ignorant," a source explained to Radar Online on Nov. 16. "Nobody on the show really likes her.”

Marroquin and DeJesus recently confirmed that they were dating and began to enjoy a number of vacations with each other in the weeks that followed. Most recently, they appeared to be together in Florida, where they shared a sexy video of themselves dancing to salsa music on Instagram.

Still, despite their romantic moments with one another, Lowry doesn't feel that the attraction is mutual and genuine. In fact, she reportedly believes the couple is dating just for spite and publicity.

“Kailyn [Lowry] can’t help thinking that Javi [Marroquin]‘s main reason for dating Brianna [DeJesus] is to spite her. There are a million other girls out there, but Javi chose to hook up with another Teen Mom star, which he must have known would result in tons of publicity," a source told Hollywood Life.

"It’s not even like it’s convenient for them to be together — they live over a thousand miles away from each other, so it just doesn’t make any sense to Kailyn," the insider added. "Each time she has to look at photos of the two of them together or see yet another story about them dating, it’s like a stab in the heart, and it’s driving her crazy."

In addition to her 3-year-old son with Marroquin, Lowry is mom to oldest son Isaac, 7, who she shares with ex-boyfriend Jo Rivera and 3-month old Lux Russell, who she shares with ex-boyfriend Chris Lopez.

To see more of Kailyn Lowry, Javi Marroquin, Briana DeJesus, and their co-stars including Leah Messer, Jenelle Evans, and Chelsea Houska, tune into new episodes of Teen Mom 2 Season 8 on Mondays at 9 p.m. on MTV.

Javi Marroquin is also set to star in his own spin-off special, Being Javi, at some point in the coming months.
