For the first time in Spanish-language television history, rival networks Univision and Telemundo--as well as NBC--joined forces to simultaneously air Jennifer Lopez and Marc Anthony’s Somos Live! benefit show for Puerto Rico.
Lopez kicked off the event with a performance that raised some eyebrows.
J-Lo turned around during her performance and "twerked" for a solid 13 seconds. Viewers were saying it wasn't the best time and place to be dancing like that.
Demi Lovato, Bruno Mars, and many other mega-stars also performed at the Puerto Rico relief fundraiser.
