Kailyn Lowry is not happy with her former friend, Christina "Peach" Pietrobon, who has grown quite close to her soon-to-be ex-husband, Javi Marroquin.

On Thursday, the women engaged in an online dispute after the Teen Mom 2 star called out Pietrobon for talking about her and her marriage on Twitter.

In response to Lowry's tweet, Pietrobon called Lowry a hypocrite and pointed out that she had been talking about her online as well.

Following Lowry and Marroquin's split, Pietrobon and Marroquin have been seen together and frequently tweet to one another online. Marroquin also recently called Pietrobon his "ride or die," but contrary to belief, they aren't dating. In fact, Pietrobon has a boyfriend.

Still, Lowry isn't happy and recently suggested that Marroquin and Pietrobon were only friends because they didn't like her.

Kailyn Lowry and her family are currently in production on Teen Mom 2 season 7B.
