Pitch Perfect 2 Trailer: Commando "Fat Amy" Flashes the President [WATCH]

It is hard to get through the opening part of the second official trailer for Pitch Perfect 2 without laughing.

The clip starts off with Fat Amy, played by Rebel Wilson, soaring into the stage, suspended in the air. The material that she is sitting on rips and causes Amy to suffer from a wardrobe malfunction. Much to everyone's surprise, Amy had gone "commando" and slowly flashes the audience, which includes the president.

Now, in the Pitch Perfect Sequel, the Barden Bellas must fight for a chance to be reinstated. However, the only way they can do it is by winning the world championship of acapella, which has never been won by an American team before.

Led by Beca, played by Anna Kendrick, the Bellas travel across the world to compete against some very serious European teams.

The two and a half minute long sneak peak is also filled with a lot girl bonding around a camp fire, several jokes, one of them poking fun at World War II and of course, singing, as the girls take on Miley Cyrus' "Wreaking Ball" and Beyoncé's "Who Run the World?"

The movie will feature Brittany Snow, Alexis Knapp, Anna Camp, Hana Mae Lee and Skylar Astin, and newcomer Hailee Steinfield
