Is it really over between Morgan Simianer and Jackson Michie? A source close to the Cheer star tells E! News that Morgan is single and has split from Jackson, the winner of Big Brother 21. 

The reality stars sparked dating rumors last December, when the two appeared in multiple social media posts together and routinely commented on one another's pages. Fans were excited about the potential romantic pairing, writing comments like, "When big brother and cheer world collide," and "The crossover I never knew I needed."
