Relationships can be a challenge, and Chris “CT” Tamburello knows that.

The Challenge star, 44, and OnlyFans model Catalina Hager have broken up less than three months after going public with their romance.

A rep for Tamburello did not respond to PEOPLE’s request for comment.

The pair made their relationship Instagram official on Sept. 3 with a since-deleted Reel. On Nov. 20, Tamburello posted a photo of Hager, 38, on Instagram and wrote “how grateful I am” for her.

“Life wouldn’t be Life with you,” the reality star captioned the since-deleted picture.

Three days later, Tamburello claimed that Hager cheated on him by posting a seven-minute video on Instagram featuring alleged messages between her and other men. Hager denied cheating, claiming the conversations took place on OnlyFans as part of her job. “He is not well,” she commented on Tamburello’s since-deleted video of the messages.

On Monday, Nov. 25, Tamburello apologized on Instagram, writing on a photo of The Joker: “I apologize to everyone for any inconvenience my slip of the SEND yesterday may have caused. I[t] appears I spoke a bit too soon and way out of pocket. Moving forward, I’ll keep matters like this in house.”

He specifically addressed Hager in the image’s caption. “I’m so sorry I hurt you,” Tamburello wrote. “I understand this probably won’t change anything. And even though we already spoke about it, its only that right that I give you a public apology. 🌳”

The Traitors season 2 winner seemed to reference the breakup in a Nov. 24 Instagram post asking the Lord to “give the ones we love the strength and courage to turn around and step into your light.”

“I pray for the guidance to pay forward the Light that was giving to me,” Tamburello captioned a video of a boat marina. “And forgiveness for any burden I may have caused…”

The breakup with Hager comes two years after Tamburello filed for divorce from his wife of four years, Lilianet “Lili” Solares. Tamburello and Solares, 33, welcomed son Christopher “C.J.” Tamburello in 2016 and tied the knot in a two-part MTV special titled CT’s Getting Married in 2018.

In April 2023, Tamburello expressed his frustrations with the divorce proceedings after he and Solares reached a temporary court agreement regarding finances and custody that included Solares conceding to move out of the home she shared with Tamburello and into a rental property to which he would contribute $7,200. Tamburello also agreed to provide Solares with an additional $761 a month in temporary support.

“I’m hemorrhaging for the next how many months paying for everything,” the MTV star complained in a since-deleted Instagram post.

Tamburello and Solares finalized their divorce in November 2023. According to TMZ, Tamburello agreed to pay his ex-wife $761.39 in child support each month and an additional $332.45 for each week he is away working and unable to look after their son. Tamburello got to keep the house he and Solare shared, but he had to give her $30,000 for her portion of the property’s equity.

An agreement about how they’d parent their son showed, per TMZ, that Tamburello and Solares can’t ask C.J. about the other parent during their time with him, and the exes can only call twice a day on days when C.J. is with his other parent. However, C.J. can initiate calls with either parent as often as he’d like.
