The Bellas and Green Bay Packers aca-battle in 'Pitch Perfect 2' trailer

Apparently the biggest battle of Super Bowl XLIX wasn't between the Patriots and the Seahawks

The new, 40-second trailer for Pitch Perfect 2 dropped at the end of the first half of Sunday's big game and featured a whole lot of aca-awesome singing battles, including a "Bootylicious" performance by the Packers (which is totally better than playing in the Super Bowl)

The Bellas return to the stage on May 15.
