Kelly Rowland, Trey Songz Duet at 2011 BET Awards

While Chris Brown took home the most wins at the 2011 BET Awards Sunday night (June 26), and Beyonce wowed with a satellite broadcast from the U.K.'s Glastonbury festival, it was former Destiny's Child member Kelly Rowland's sizzling performance with Trey Songz that was the night's unexpected highlight, receiving perhaps the biggest audience response of the evening.

Stripping down for a topless rendition of 'Love Faces,' Songz further riled up the the female quotient of the crowd at the song's end, quipping, "I wouldn't be me if I ain't get a little nasty," and tearing into an inspired rendition of his recent single 'Unusual.'

"Even I need a little 'Motivation,' Songz then announced, introducing Kelly Rowland to the stage in an all black outfit and black hat, accompanied by several topless male dancers in leather harnesses. Although Songz finally put his shirt back on, things got extremely heated between the two crooners as they belted out Rowland's chart-topping new hit 'Motivation,' with Songz embracing her neck as the couple dropped slowly to the floor -- a steamy end to their duet was met with wild applause and a standing ovation from the crowd.

Rowland's third album 'Here I Am' is reportedly in stores July 26.
