The show takes place today at New York City's Columbus Circle at 3pm ET -- portions of the concert will air on the NFL Network starting at 3:30pm ET, and they'll also be streamed on NFL.com from 4pm to 7pm. The concert leads right into the opening game, as the New York Giants take on the Washington Redskins on NBC-TV.

At a press conference yesterday, Usher and Keith admitted to being Tennessee Titans fans, while Natasha, not being American, owned up to not knowing that much about football; she prefers rugby. However, all picked the Giants to triumph over the Redskins tonight. Usher also inadvertently revealed this season's Super Bowl halftime performer: he stated confidently that it would be BRUCE SPRINGSTEEN, which has been rumored. But an NFL official was quick to say that wasn't accurate -- that they're, quote, "still working on it."

After the press conference, Usher told us he's really more of a basketball fan -- he's the co-owner of the Cleveland Cavaliers -- but likes football as well. He said he was happy to have his mom, JONETTA, back in the fold as his manager; he'd previously fired her, but has now rehired her. And he revealed that at today's show, he'll be performing his new single, "Trading Places," with special guest star WILL.I.AM.

Natasha told us that her boyfriend, who's American, is the one who explained the rules of football to her. She says, "I'm a complete beginner to it, but it's kind of fun and fascinating."
