The 2012 Brazil Carnival was in full swing in Rio de Janeiro with millions of spectators viewing the celebration. Among the celebrities attending the famous event were Black Eyed Peas singer Fergie, and American Idol judge Jennifer Lopez.

It had recently been reported that JLo would attend the event, and now Washington Post reports she was in fact there. According to their article, Lopez was there thanks to the promotions of beer company Brahma. Meanwhile, Fergie was there for Head and Shoulders. Apparently, neither of the two singing stars were part of the parade, but JLo was seen waving to the people on hand from high up in her VIP seats.

Other celebs who have attended this event in the past include Beyonce, Paris Hilton, Kevin Spacey, Madonna and Pamela Anderson. While Jennifer Lopez wasn’t necessarily part of the parade, she was required to appear in localized TV ads for Brahma beer. In the ad, she is seen doing the samba. The commercial’s director said of JLo’s ability to pick up the fancy footwork fast:

“On the day of the shoot, Jennifer arrived, went to makeup and then learned to samba in half an hour. She has this Latin swing, and it was really easy for her to learn.”

It can’t be all that hard for Lopez to learn to samba. After all she’s been dancing in her own music videos for years, was a backup dancer for MC Hammer, and also one of the Fly Girls on In Living Color. So there’s no surprise that she’d pick up these dance moves so quick. She may not currently be dancing so much as she’s sitting down watching people sing, but don’t let that fool you.

It’s great to see the celebrity involvement in the 2012 Brazil Carnival as well. One of the biggest guests of them all was none other than “MacGyver” actor Richard Dean Anderson who was a guest in Salvador’s celebratory parade. The fact that such a wide variety of US stars comes out to support this event in Brazil shows the magnitude of the celebration which reaches all corners of the world.
