"Teen Mom 2" star Kailyn Lowry is reportedly upset that her ex-husband, Javi Marroquin, took her MTV co-star, Briana DeJesus on a Disneyland vacation with her sons, Isaac and Lincoln. Kailyn and Javi have been divorced for months and separated even longer. However, it seems that she may not be entirely comfortable with the rumors that Javi is dating Briana, and spending so much time with her.

Kailyn's not happy about Javi and Briana's Disney trip

According to Hollywood Life, Kailyn Lowry was not happy when she found out that Javi Marroquin had invited Briana DeJesus and her family along to a Disneyland family vacation that her sons were attending.

One insider claims that Kail was more than angry when she found out that Briana had been invited along on the trip, and that she can't stand the thought of her "Teen Mom 2" co-star playing step-mother to her sons. Although Lowry knows she can't tell Javi who he can spent time with, she reportedly can't help but express her opinion on the whole situation.

Javi's gushed over Briana in the past

Javi Marroquin and Briana DeJesus' joint family vacation comes after months of rumors that Javi and Briana may be a bit more than friends. The pair has been friends for years, and have maintained a relationship on and off camera. When Briana was asked to join "Teen Mom 2" after her show, "Teen Mom 3" was canceled, it seemed that Javi would have more of a chance to see his friend, who lives thousands of miles away from him.

Later, Javi admitted that he would "be open" to dating Briana and gushed over how much he likes her and her family.

Kailyn won't appear on the 'TM2' reunion

It seems that Kailyn Lowry, Javi Marroquin, and Briana DeJesus could all be asked about the awkward situation during the upcoming "Teen Mom 2" reunion special. However, Kail has revealed that she does not plan to attend the taping of the reunion, and says it is due to not wanting to travel with her newborn son, Lux Russell, whose father is Chris Lopez.

Kail says she doesn't want to fly across the country with the infant, and that she refuses to leave the baby while he is still so young. Maybe Kailyn can video chat into the discussion so that she can answer a few questions with host Dr. Drew.

Will the new coupling be announced at the reunion?

Meanwhile, "Teen Mom 2" fans are hoping that Javi Marroquin will have plenty to say about the situation with Briana DeJesus and Kailyn Lowry.

It looks like the situation could get a bit uncomfortable, but Javi has seemingly been open and honest about his relationships up until this point. Fans will just have to tune in to see if anyone spills any juicy information about the alleged relationship when the show airs.
