Teen Mom 2 star Kailyn Lowry makes some serious allegations against her ex, Javi Marroquin. She claimed that he was cheating on his fiancée throughout her entire pregnancy.

Marroquin - who was once married to Teen Mom's Lowry - and Comeau were dating on and off for about a year before welcoming their son Eli in November 2018. On June 17 this year, the couple announced their engagement. But their bliss was short-lived when, exactly two months later, on August 17, police were called to their home in Delaware following a dispute. Marroquin told the 911 dispatcher he wanted to get someone out of his house, who he later said was his sister Lidia. Following the incident, Comeau unfollowed her fiancé on Instagram and deleted photos of them together, leading fans to think the couple had officially ended things. While no more details about their argument have been made public, Marroquin recently offered an apology to his family on Instagram.

On Tuesday night’s episode of Teen Mom 2 (via People), the mother of three claimed that her ex-husband Marroquin had been unfaithful to his fiancée Lauren Comeau. Lowry made the allegation after the Teen Mom producer, Patrick, asked her about the photos posted on Instagram of Marroquin and Comeau being engaged. Patrick asked Lowry, "Did you see this? Javi and Lauren are engaged." Lowry responded, "Yes, I already knew it was happening. I didn’t know he actually did it but I knew it was going to happen." In which the producer asked her, "Oh, are you going to congratulate them?" Lowry laughed and said, "No," and added, "Congrats! Good luck, he’s been cheating on you since you were pregnant!"

Earlier in the episode, Lowry alleged Marroquin had shown up outside her New York City hotel room as they were filming the Teen Mom 2 reunion earlier this year. Lowry claimed, "He tried to f*ck me, and I was like no." The allegations from Lowry that her ex-husband Marroquin has been cheating on his fiancée, Comeau since 2018 came to quite a shock to the Teen Mom 2 audiences. Though, now the lengthy and vague apology that Marroquin posted on Instagram to his finacée makes a little more sense that there may have been cheating involved.

Though there is no proving that anything that Lowry said was the truth, however, she did claim to be the first one that Marroquin called after his huge fight with Comeau. Though she promised she would never go to magazines to reveal the truth about what happened that night, she did, however, drop a big bombshell on the last episode of Teen Mom 2.
