According to People, the former Olympian wants the two to reunite after they announced their split earlier this week.
"I hope for the best… I love Reggie. Reggie's a great guy. I love Kim. She's just a super sweet, great human being," he said. "It's two very successful people, and it's not easy."
Asked whether he thinks the couple will eventually get back together, the ex-athlete responded: "I try not to pry into what they're doing. I really haven't talked to her about this… Who knows what's going to happen?"
