The singer, who vowed he would water ski naked in Florida's Biscayne Bay if his beloved Spanish soccer team won the World Cup back in June, did just that at the end of July.
Despite his concerns about sharks and law enforcement, Iglesias, 35, made the late-night ski trip with a video camera to record the stunt.
Though the footage, originally posted on TMZ, is dark and shaky, the singer is clearly nude – and possibly freshly groomed.
"I need to get my Brazilian wax before I do it," he joked to PEOPLE last month. "A bet's a bet."
But is it really him in the video?
Reps would not confirm. but they did say that the singer was in Miami the last week in July.
