Kelly Rowland Breaks Down While Singing About Her Jealousy Of Beyonce

Kelly Rowland broke down into tears last night in Washington, D.C. while performing her new song about her jealousy of her former Destiny's Child bandmate Beyonce.

After singing the lyrics "Turnin' me against my sister" from her "Dirty Laundry" track, Kelly took a tearful 20-second time-out. Overcome with emotion, she hunched over in her seat and cried with her hair draped down, covering her face.

The crowd then chanted her name in support. The songstress regained composure and resumed singing.

"When my sister was on stage killin' it like a motherf***er/ I was enraged, feelin' it like a motherf***er," she sang. "Bird in a cage/ You would never know what I was dealin' with/ Went our separate ways but I was happy she was killin' it. Bittersweet she was up, I was down/ No lie, I feel good for her but what do I do now?"

She sings that Beyonce was on fire post-"Survivor," but no one wanted to hear her "bulls**t." She also references her BFF by name later in the song. Kelly sings that she was in an abusive relationship and her boyfriend turned her against Bey.

"I was battered/ He hittin the window like it was me, until it shattered/ He pulled me out, he said, 'Don't nobody love you but me/ Not your mama, not your daddy and especially not Bey.'"

Even though Beyonce has had one of the most successful years of her professional life, Kelly's career has also taken off in the last month. Her fourth album (which features the song "You've Changed" -- a collaboration between the Destiny's Child ladies) will be released on June 18 and her Lights Out Tour will end on June 28. Kelly also recently joined The X Factor judging panel.
