One Direction vs. Drew Brees!

The British boy band battles with the New Orleans Saints quarterback over a can of Pepsi in a new commercial for the "Live For Now" campaign. 

"We like to work really hard when it's work time, but then we like to have a lot of fun as well," Harry Styles, 18, explains of joining the campaign. "So I think 'Live for Now' is kind of that."

In a behind-the-scenes video, Styles, Niall Horan, 19, Zayn Malik, 19, Liam Payne, 19, Louis Tomlinson, 20 and Brees, 33, try to one-up each other to win the Pepsi.

And it results in Brees trying to sing with the band to their hit "Live While We're Young."

"I got to sing with One Direction today, but I can't say that I had musical aspirations growing up," Brees says. "I realized I had zero talent in that department at a very early age."
