Bruce Jenner has revealed what he really thinks of Usain Bolt calling himself the "greatest athlete to live."

TMZ caught up with Jenner at an airport in Los Angeles several days after the 25-year-old made the comment: "I'm now a legend. I'm also the greatest athlete to live."

"He's the best sprinter," Jenner said. "He can't pole vault, he can't throw anything ... that's an athlete," he added.

In an exclusive video the 62-year-old star of "Keeping Up With The Kardashians" explains that decathletes are ranked the highest of all athletes and that they are considered the "most athletic." 

When the reality star was asked his opinion on whether Bolt could compete in a decathlon, he replied: "He would be terrible."

Jenner had won a gold medal for the decathlon in the 1976 Olympics. 

TMZ reported that Bolt made the comment at a press conference after winning the 200 meter final.

"I am in the same category as Michael Johnson," he added. "I'm honored. It's all about Michael Johnson for me."

Usain Bolt added to his collection of gold on Saturday. He earned his third gold at the 4x100 Meter relay. He also gathered 3 gold medals from his successful runs during the Beijing Olympics.

While taking gold in the Men's 100M Final, Bolt set a new Olympic record time of 9.63 seconds; the second fastest time in history.
