B.o.B, Hayley Williams Soar Through 'Airplanes' At EMA

Paramore singer begins ethereal hit for show, which airs Sunday at 9 p.m. ET on MTV2.

B.o.B and Hayley Williams may not have met until months after they crafted their chart-topper "Airplanes," but that hasn't stopped them from bringing great chemistry to their stage performances. During the 2010 MTV Europe Music Awards in Madrid on Sunday (November 7), the duo rocked their hit at Caja Magica.

The flame-haired Paramore singer began the set solo, crooning the chorus from the bottom of an intricate, azure-hued, circular structure, wearing a black sweater, pale lipstick and dramatic eye makeup. B.o.B then appeared in the middle of the set piece, which resembled a tunnel with several inner layers leading to a gaping hole. Rocking a plaid vest and dark shirt, he spit his lyrics as he descended the staircase.

The duo added an interactive element to the performance, dropping pale balloons onto the crowd from the ceiling. The audience batted the giant spheres, which were nearly the same size as the performers, toward the stage.

The duo also performed their top-five hit at the 2010 MTV Video Music Awards in September, but switched it up for the EMA event, focusing on "Airplanes" instead of working in a medley alongside "Nothin' on You"

hook jockey Bruno Mars. However, the elements that went into making the VMA performance memorable were intact for the EMA show.

When MTV News caught up with B.o.B before the VMA show to find out what fans could expect from the onstage collaboration, he said it was all about seeing the hip-hop star and the rock vocalist interact with each other.

"I think just the fact that me and [Williams] are performing on the stage at the same [event] is gonna be spectacular," he said.

The 2010 EMA show airs on MTV2 on Sunday (November 7) at 9 p.m. ET, and an edited, performance-heavy version will be broadcast Friday at 9 p.m. ET on MTV.
