Blake Shelton and Gwen Stefani were showing off the sporty side of their new relationship when they attended the Arizona Cardinals versus Green Bay Packers game on Sunday in Arizona. Though they were busy cheering for the Cardinals, they managed to snag quite a few selfies.

The No Doubt singer wrote "#football @AZCardinals @blakeshelton Eeeeeekkkkk! @NFL" on a photo of her with Shelton and friends at the game.

It looks like they were having a ball and not just because the Cardinals were winning. They even took a photo with fellow celebrity Cardinals fan, David Spade.

Stefani supported her new man's team with a Cardinals hat, jeans splattered with gold paint, and topped off the look with bright red accessories and lips to match.

The couple have been officially dating since November. Earlier this month, Stefani shared a sweet video of the couple kissing on Twitter. The mother of three also reportedly spent the holidays with her new man in Oklahoma.
