Jennifer Lopez is still hurting from her tumble at the American Music Awards, it would appear. Skip related content The 40-year-old singer laughed off the slip at the time, but revealed on the Ellen DeGeneres Show that she is still a little sore. "I have a bruised bone," she said in reference to the incident which saw her land squarely on her backside. Jennifer also explained what went wrong in the routine in which she needed to climb over semi-naked male dancers. She told Ellen that unlike in rehearsals, when the men were fully clothed, the live performance saw them dispense of their tops, exposing their sweaty backs. "When I stepped on their backs my feet got wet. "So when I landed, it just slipped from under me," J-Lo said. Sources: SINA.com
