Viewers of this upcoming Sunday’s Super Bowl halftime show might notice a little something extra: time.

Usher, the velvety-voiced King of R&B and all-around ageless hottie, tells EW that he and his team were very “strategic” while creating his supersized Las Vegas performance.

While most performers are tasked with condensing their entire music catalog into an incredibly tight show that runs around 13 minutes, Usher reveals that he managed to get 15.

“I can’t explain why, but it’s a funny thing that I was able to do and craft,” Usher explains ahead of the big game. “That was a huge strategic thing that happened between me and my agency.“

The 45-year-old says he’s not nervous about performing on the biggest stage in the world (“Anxiety, but no, not nerves”), which he sees as a culmination of his Vegas residency that ran for two years and 100 shows. The Super Bowl will be his 101st show and thus, he says, a time for him to “finally celebrate” what he accomplished.
