Kelly Clarkson was struggling to get through her residency show in the days leading up to her ex-husband Brandon Blackstock’s shocking death. The singer, 43, broke down crying during her July 26 Las Vegas Studio Session residency concert while introducing fans to an updated version of her song “Piece by Piece.”

I’m really trying to pull it together,” Clarkson said, wiping back tears during a performance that was caught on video.
