Mountain Dew and Doritos are going head to head in a one minute-long commercial during this year’s Super Bowl, marking the first time ever that two brands have advertised back-to-back during the big game.

Mountain Dew and Doritos announced they are adding two new names to the celebrity roster that already includes Morgan Freeman and Peter Dinklage: hip-hop legends Missy Elliott and Busta Rhymes.

The second teaser, seen here, pairs Missy with Morgan Freeman for MTN DEW ICE and Busta with Peter Dinklage for Doritos Blaze in an epic battle. Each duo is practicing a series of tongue twisters in the mirror before they depart for a testy showdown.
