Blake Shelton and Gwen Stefani are on cloud nine together!

The couple, who hasn't been shy recently about showing off major PDA, flew to Arizona yesterday to see the Green Bay Packers play the Arizona Cardinals in an NFL football game. Gwen, 46, snapped a pic with Blake and their friends on the way to the game, and judging by her caption – which said, "Eeeeeekkkkk!" – she was clearly excited.

According to E! News, The Voice couple was very affectionate during the game.

"They were sitting close and holding hands at a point. They were extremely friendly to fans, players and the people around them," a source said. "Blake loves football and is a big fan of the Cardinals so it was nice that Gwen saw him in his sport element."

The Cardinals head coach Bruce Arians even hung out with the couple after the game and commented on how great it was to finally meet the 39-year-old's new beau.
