Kelly Rowland broke down in tears while performing her new track 'Dirty Laundry' - a song about her previous jealously of best pal Beyonce - during a show in Washington this week. The crowd cheered for the R&B singer during her tearful delivery of the emotional song, leaving Rowland to stop and wipe away the tears.

In the new track, the former Destiny's Child singer speaks about how her abusive former boyfriend turned her against Beyonce. "Bird in a café. You'd never know what I was dealing 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. In a video from the Washington gig, Rowland, 32, is seen sitting on a stool and singing before choking up and having to bow her head. Buoyed by the crowd, she continues the song before telling fans, "Doing this song for me was so therapeutic. Honesty, like my mama always says, is always the best policy."
