Kelly Rowland was two-thirds into her live performance of her "Dirty Laundry" single during her "Lights Out Tour" kick-off show in Washington D.C. when the 32-year-old singer suddenly broke into tears. The emotional track from her forthcoming album "Talk a Good Game" made the pop/R'n'B star cry in front of the crowd that went to see her sing onstage at The Fillmore Silver Springs.

"He turned me against my sister, I missed ya," Rowland sang before breaking down, obviously overcome with emotion as she sat hunched on center stage, keeping her face away from her audience. It seemed for a moment that she might not be able to continue with her performance, but as the crowd cheered her on, Rowland wiped the tears and continued singing.

The outpouring of emotion stems from the fact that the single is Rowland's confession song, where she admits about being jealous of her Destiny's Child sister Beyonce Knowles while they were together in the group. She also gets to reveal through the song that she was once involved in an abusive relationship.

While Beyonce has clearly outdone her DC group mates Rowland and Michelle Williams (II), Rowland actually says she is happy for all the individual success that came Bey's way as she has likewise found her own groove, working on her solo career at a steady pace. She had just joined Mexican singer Paulina Rubio as the new judges on "The X Factor (US)", replacing record executive L.A. Reid and pop superstar Britney Spears.
