The Bellas now have it big time and they are tapped to perform for the president of the United States on his birthday.

The new trailer for the upcoming sequel of the musical comedy film "Pitch Perfect" shows how that presentation goes out of kilter. In the first second, Fat Amy rocks Miley Cyrus' viral song "Wrecking Ball" as she sashays through the center of the stage. The next second, she has everyone covering their eyes and gasping for her accidental flashing. 

Apart from a "commando" situation, her wardrobe malfunction gets her award-winning singing clique suspended. But it is not only their suspension they have to deal with but also the European champions, who now think they are a "heated mess" and are slowly kicking them out of the limelight. 

"Pitch Perfect 2" follows the Bellas' quest to win the World Championship of A Capella and make history by being the first Americans to take home the trophy. All that while they struggle with the aftermath of the group's disastrous showing. 

Of course, the Barden Bellas puts up a fight as they prove to their contenders and to the world who really rules the stage. In the trailer, the songsters rock and groove to "Run the World" by Beyonce as the audience claps and screams in glee. The Bellas are indeed a strong team, doing what they do best as a family while having fun in pillow fights, awkward dances and crazy pool parties.

Ultimately, the movie will again feature feisty a capella showdowns as well as Beca's and Fat Amy's wise-crack rejoinders to mockers who laugh at their talent. Sure enough, "Pitch Perfect 2" will be a barrel of laughs and those who have been waiting for this follow-up are sure to get pumped even more. 

"Pitch Perfect 2" stars Anna Kendrick, Rebel Wilson, Elizabeth Banks, Hailee Steinfeld, Brittany Snow, Alexis Knapp and many others. The musical comedy will be out on May 15.
