Jennifer Lopez [1] can't do anything without being supersexy. Even when filming the music video for her new upbeat song "El Mismo Sol," [2] an English remake of the Summer hit by Spanish singer Alvaro Soler, J Lo oozed hotness while gyrating on a carousel. Wearing floral-printed shorts and a bustier (throwback to her Selena days), the star danced and sang to the new tune, later changing into a chic '70s look [3] to film scenes in the streets of Brooklyn. Alvaro was also on hand to film scenes with Jennifer and was seen laughing with her rumored boyfriend Casper Smart behind the scenes.
