The special day was organized by Johnson with celebrity wedding planner Sara Fried of Fête Nashville.
Although the former Olympian – and Dancing with the Stars champ – admitted to a few pre-wedding jitters, the outdoor ceremony, held at a private farm in Franklin, was exactly as she hoped: "intimate and relaxed."
Johnson and East, 24, a former player at Vanderbilt University who was recently signed by the Oakland Raiders, met about three years ago through East's brother, a fellow athlete. The couple lives in Nashville.

"Everything is right about him!" Johnson told PEOPLE.
"The more I wasn't trying to impress him by being that celebrity girl or Olympic gymnast, but was just my weird, awkward self, the more he loved me. And it just became more and more comfortable."
