Usher's club-rattling jam "OMG" may "kill it every night" according to tourmate Miguel, but when the Atlanta crooner hit Madison Square Garden earlier this week, he was almost taken out by a clumsy fan.

When the singer touched down in New York on Monday, he indulged a super amped fan's fantasy by pulling her onstage for an intimate flirty serenade of "Trading Places." As Usher and the concertgoer got cozy on a recliner, she swiveled around to face the crooner — knocking him squarely in his mug with her foot. She began apologizing profusely as Usher briefly paused to collect himself. But the superstar took the strike in stride, quipping, "We play rough in the bed. We kick each other in the face and all type of good stuff."

Although Usher brushed off the blow, the moment did make an impression on him.

"In all my years, this is one of the most interesting experiences. I got a kick out of it!" he told Us Weekly. The singer assured fans that the knock wasn't that bad. "It looked worse than it actually was. My audience and I got a good laugh."

As for the fan, the "DJ Got Us Fallin' In Love" star maintained everything is all good on that front too. "Wherever you are baby, don't feel bad," Usher said. "No hard feelings."

As Miguel has noted, Usher isn't one dwell on drama, whether it's cranking out another hit album or weathering an unexpected hit from a fan.

"He's such a tremendous example of perseverance and determination," Miguel recently told MTV News. "I was there throughout this album, so I've seen the adversity that he's had to overcome perception-wise."
