The former Destiny's Child star was belting out her controversial new track 'Dirty Laundry', which chronicles the singer's feelings of jealousy towards Beyonce as her solo career took off while she was battling personal problems at home, reported Us magazine.
About starting the song, the 32-year-old singer gets choked up just as she sings the line "Turnin' me against my sister," in reference to Beyonce.
The powerful ballad, which Rowland released earlier this month, addresses her past relationships with abusive boyfriends, as well as her jealousy from Beyonce's success.
