Nelson told TMZ Sports that he and the Real Madrid star were hanging out after the Portuguese national team held a practice at the Jets' facility in New Jersey. Ronaldo was trying to throw a football but couldn't quite master the technique.

"He was throwing it around, but he couldn't get it to spiral," Nelson said. "He wasn't holding it right. He was grabbing it in the middle and shot-putting it."

But after just a few minutes, Ronaldo was throwing like a pro. (Watch the video below.)

Ronaldo was recently named No. 1 on the list of most marketable soccer players, ranking the highest on the latest Celebrity Davie-Brown Index, an index for brand marketers that quantifies perceptions of famous entertainment-industry, sports and other personalities.

Ronaldo is also the soccer star with the most Twitter followers out of all players in the World Cup. As of Thursday, he had 26.7 million followers.

He also recently won his second FIFA Golden Ball for the player of the year, becoming the first-ever Portuguese player to receive the honor twice.

The World Cup kicks off Thursday in Brazil.
