Jenny from the Block was in London over the weekend to perform at the big Capital Radio Summertime Ball held at the Wembley Stadium.
J.Lo performed some new songs along with some oldies but goodies. She also walked the red carpet wearing what is possibly the ugliest outfit we've seen her in.
Other performers included at the ball included Nicole Scherzinger, Jessie J, LMFAO, Cee-Lo Green and Far East Movement.
Nicole was really excited about her performance Tweeting, "Just arriving Wembley Stadium #Rightthere! For the Capital Radio Summertime Ball! I can't wait!"
Below is a video of J.Lo’s performance of “Get Right” from the concert.
