'Teen Mom OG' Cast to Include 'Are You the One' Star Cheyenne Floyd

An MTV alum is joining the cast of the upcoming reality series Teen Mom OG. The network announced that Cheyenne Floyd would appear on the show with her daughter, Ryder, in an Instagram post on Thursday.

"Welcome to the #TeenMomOG family, Cheyenne," the network wrote alongside a photo of Floyd holding her daughter.

Floyd made her MTV debut when she first appeared on Season 3 of Are You the One. The reality star later joined the cast of The Challenge: Rivals III, where she placed third.

It was during her time on The Challenge that she met co-contestant Cory Wharton, with whom she co-parents her daughter. Wharton also appeared on subsequent seasons of The Challenge, including Invasion, Dirty 30, Champs Vs. Stars and the latest installment, Vendetta, on which he revealed he was expecting a child with his ex, Floyd, despite being in a relationship with co-star Alicia Lavida.

Wharton hinted at his appearance on Teen Mom OG in a post on Twitter, although it's unclear how big of a role he will have on the show. "Is the world ready to see me as a dad?" he wrote on Thursday.

Wharton also retweeted MTV's announcement of Floyd's casting and wrote, "TEEN MOM OG here we come October 1st!!"

Fans were shocked when the duo announced they welcomed a daughter back in December 2017. Both TV personalities shared the same family photo on their social media, revealing Ryder for the first time.

Floyd's addition to the Teen Mom OG cast comes two months after it was announced that Bristol Palin would also appear on the show. Levi Johnston, Palin's ex-fiancé and the father of her 9-year-old son, Tripp Johnston, is also slated to make an appearance with his wife, Sunny Johnston.

Teen Mom OG is set to premiere on MTV October 1 at 9 p.m. ET.
