First, Lochte was asked in an Aug. 3 radio interview by Ryan Seacrest, who is contributing to NBC's coverage of the Games, whether any of the athletes urinate in the pool.

"Of course," he said. "I think there’s just something about getting into chlorine water that you just automatically go."

Then earlier this week, Phelps told the Wall Street Journal that it isn't really that big of a deal.

“I think everybody pees in the pool,” Phelps said. “It’s kind of a normal thing to do for swimmers. When we’re in the water for two hours, we don’t really get out to pee.”

His further justification: “Chlorine kills it, so it’s not bad.”

But Cameron wasn't happy to hear the news.

In an interview with the U.K.'s Metro newspaper, he said: "I was quite surprised by that. It is not OK to pee in the pool."
