Viral WATCH: Bieber & Dancing Caveman 'Gronk' Team Up in Super Bowl Ad
Singer Justin Bieber, New England Patriots tight end Rob Gronkowski and former NFL wide receiver Terrell Owens have teamed up to appear in a Super Bowl commercial.
The commercial explores the history of touchdown celebrations.
Bieber, who declares himself a celebration expert, first mentions the high-five, in which Gronkowski, dressed as a caveman, high-fives a fellow caveman. Gronkowski, who is not playing in Sunday's Super Bowl due to injury, then shows the evolution of celebrations by spiking the football, in his patented "Gronk Spike" technique.
Bieber then discusses several other touchdown celebrations before introducing Owens, who famously borrowed a cheerleader's pom-poms for a celebration while playing for the San Francisco 49ers.
The ad is for T-Mobile's new unlimited data plan.
Watch the commercial above, and tune into the Super Bowl at 6:30 p.m. ET Sunday on Fox.
