Beyonce Live Performance at Kobe Bryant Memorial Service

Beyoncé Knowles-Carter opened the memorial being held Monday at the Staples Center in Los Angeles honoring Kobe and his 13-year-old daughter Gianna, as well as seven other victims who died in a helicopter crash last month. She began her performance with her hit single "XO," from her 2013 self-titled album. "I'm here because I love Kobe and this was one of his favorite songs," Beyoncé said while backed by a choir and violinists clad in all-white. She then delivered a moving rendition of "Halo," drawing applause from Vanessa Bryant.
