Jennifer Lopez visited Brazil with boyfriend Casper Smart two weeks ago to participate in the Carnival, and now pictures for the star have just been released. The "American Idol" judge showed her hot body in sexy yellow bikini, as she and Casper joined a few friends for a relaxing yacht cruise. The pictures' release comes a day after J. Lo and ex-husband Marc Anthony's show "Q'Viva! The Chosen" made its debut in the States on the FOX network. Lopez is confident that the talent seeking program would find success, as she said: "I think it'll do fine. People are used to seeing different languages on TV. And I think when shows are good, they transcend language. And I think this one is good.”
