Outside the field, Stephen is a loving boyfriend to his longtime girlfriend, Tess McCracken. The pair met while competing for Penn State University’s gymnastics team.

“Happy is what happens when all your dreams come true❤️,” Tess captioned a post to celebrate Stephen’s win.

She added, “For the entire time I’ve known you, you have been nothing but absolutely certain that one day you would be an Olympian, and seeing that dream become a reality this week is a feeling that will stay with me for the rest of my life. Stephen, you are the greatest partner, athlete, and role model. I can’t wait to see what life has in store for you next, and I will be right beside you for every moment of it🥰.”

Stephen also posts about his girlfriend regularly. He marked their seventh anniversary in 2023 with a sweet Instagram tribute.
