When ET spoke to Lochte last October, he credited Reid with helping him through the aftermath of his 2016 Rio Olympics scandal, when he and several U.S. men's swim teammates fabricated a story about being robbed at gunpoint following an incident at a Brazilian gas station.

"She stuck right there by me and just was my rock," he told ET. "That’s when I knew. I was like, 'I’m not letting this one go.'"
