Jennifer Lopez Dancing at Carnival 2012

Jennifer Lopez and Casper Smart heat up Carnival. Hey there, I'm Karli Bulnes and we've got video of JLo and Casper's trip down south in today's PopSugar Rush. Jennifer Lopez shakes it on the sidelines Sunday at Carnival in Brazil, while boyfriend Casper Smart soaks up the celebration close by! Video posted by a fan site on Facebook shows the couple, who have been dating since November, snapping pictures while hanging out on a VIP balcony. The Brazilian beer company, Brahma, brought J Lo down for the festivities after she performed a sexy samba in one of their recent commercials. Both Jennifer and Casper tweeted their excitement over being in the South American country for Carnival, and they weren't the only famous faces in the crowd. Fergie was also in attendance, and she and Jennifer are just the latest celebrities who've headed to Carnival celebrations around the world. Brazlilian native Gisele Bundchen and her husband Tom Brady popped up at the Rio de Janeiro party last year. And in 2010, Madonna raised a glass from the sidelines in Rio while Beyonce hit the dance floor during Trinidad's Carnival. When J Lo returns to the US, she'll resume her judging position on American Idol, plus, she'll get ready to share her talent competition show, Q'Viva, which is set to premiere on March 3rd.
