Priyanka Chopra did the coin flip for the Guinness International Champions Cup soccer match at Dodger Stadium in Los Angeles California on August 3, 2013, where Real Madrid played Everton. Cristiano Ronaldo is also shown in the beginning of the video while Priyanka is walking onto the field and being introduced by the public address announcer (he's also shown briefly near the end of the video).
UPDATE 8-6-2013: As I was reading through some of the comments here, and some of the comments I deleted, I realized that there seems to be a basic cultural misunderstanding here. In the United States, it's normal to have a celebrity or famous person on the field at the start of a sporting event to perform some ceremonial function. The celebrity is sometimes a singer, sometimes an actor, a pro athlete from another sport, Miss World, Olympic Gold Medalist, Hero Firefighter, Veteran, etc. At baseball games, the celebrities throw a pitch (called a "ceremonial first pitch"). At American Football games, they flip a coin. There is almost always a celebrity there to sing the National Anthem also. I'm sure it's beneficial to both the celebrity, and to the team and sport. The fans in the United States love it, and expect this kind of extra entertainment at every sporting event. Priyanka did not interrupt, or interfere with this event, or anything like that -- she was invited by the event's sponsor to be there. Also, her song "Exotic" is the official song of this "Guinness International Champions Cup" soccer tournament. And one final thing - take a look at the video on the Real Madrid F.C. official YouTube Channel of Ronaldo at Dodger Stadium three nights before this throwing the "ceremonial first pitch" among other things. We love this type of extra entertainment at our sporting events here in the U.S., and we loved having Priyanka here at Dodger Stadium in Los Angeles, California. I hope the Dodgers invite her back to sing before a game this year.
