Farrah Abraham and Simon Saran are not on good terms as they prepare for tonight's conclusion of the "Teen Mom OG" season 6B reunion special on MTV. As Abraham continues to film "Single AF" with MTV and Saran embarks on what appears to be a new romance, the former couple is feuding on Twitter.

With their fans and followers watching, Abraham and Saran engaged in a messy feud on Twitter on July 10 after Saran proclaimed that Abraham had failed to find love on "Single AF." According to Simon Saran, who announced that he would not be returning to "Teen Mom OG" at the end of last week, MTV wasted their money paying for Abraham to find a date when she ended up failing to make a love connection.

After Farrah Abraham told Simon Saran that she was happy that she gets to travel the world and meet new people who are great, unlike Saran, she accused her former boyfriend of staying at home and stalking her social media pages in an effort to keep track of her and her dates. She also said he should thank her for making him and accused him of being jealous. In turn, Saran asked Abraham why she would think he was jealous after she allegedly called him the previous night. Abraham has been traveling in recent weeks and documenting her dating adventures on her Twitter and Instagram pages.

According to Abraham, Saran is no longer in her life and is acting out because he is hurt to see her move on. The reality star also told Saran that his free ride was over and requested that he stop talking about her. "Worst free ride ever lol," Simon Saran fired back.

Farrah Abraham and Simon Saran dated on and off for a few years before parting ways earlier this year amid filming on the sixth season of "Teen Mom OG." Then, around the time that their breakup scene aired on the show, the on-and-off couple sparked rumors of a reunion when they traveled together to Jamaica in honor of the 26th birthday of Abraham.

A short time after Abraham's birthday trip, Abraham and Saran turned up in Las Vegas where they celebrated the birthday of a friend. Since then, they've kept their distance as Abraham films "Single AF," which is expected to air in the coming months.

To see more of Farrah Abraham and her reality co-stars, including Catelynn Baltierra, Maci Bookout, and Amber Portwood, tune in to tonight's second half of the "Teen Mom OG" season 6B reunion special at 9 p.m. on MTV.
