Jennifer Lopez  looked like she was hard at work when she filmed scenes for her a music video in Miami on Wednesday while surrounded by a group of hunky, bronzed men. The singer wore white hot pants while she danced on a yacht with the gaggle of guys and got very close to one handsome actor in particular. However, it was all for the cameras, as J Lo's boyfriend, Casper Smart, was also on the set, watching his loved one work her magic. Jennifer has been filming the new video clip over the past few days, even transforming one Florida street into a mini-Carnival parade  for a festive scene with Pitbull. The new video is for "We Are One," the official anthem for the FIFA World Cup, which will take place in Sao Paulo, Brazil, in June. World Cup songs can turn into big hits for stars, as Shakira 's "Waka Waka" anthem for the 2010 competition in South Africa became a massive hit on the pop charts.
