We didn't see that coming! Cory Wharton might have just revealed the best-kept secret of 2017 — the star of MTV's The Challenge: Rivals III took to Instagram on Saturday, Dec. 16 to announce that he is a proud papa to an adorable nine-month-old baby girl whom he shares with his former co-star Cheyenne Floyd! The reality star shocked fans when he revealed the news, which finally solved the mystery of the identity of Cheyenne's baby daddy.

"I’ve been off of social media for a while now…for many reasons. Most importantly God has given me the biggest blessing in my life, my daughter Ryder K Wharton," the 26-year-old wrote in his sweet Instagram announcement. "I want to say thank you, Cheyenne, for being such an amazing mother. I look forward to co-parenting with you and giving Ryder all the love in the world. I can’t wait to watch you grow up and be there for you every step of the way, love you Moochie!!!"

He also took to Instagram Live to formally introduce his baby girl to his followers and revealed some adorable details about her likes, dislikes, and her milestones. Little Ryder loves to watch the kids' show Baby Einstein, she can say "dada", and she can also crawl — and she also looks a lot like her reality TV star mama!

Ever since Cheyenne revealed her pregnancy with maternity photo shoot last October, fans have been speculated who her baby daddy could be — and many of them wondered if it was Cory because they sparked romance rumors while on the set of The Challenge: Rivals III. But now that Cheyenne is able to reveal the identity of her baby daddy, she took to Instagram to gush over Cory.
