Shelton, Stefani release "Purple Irises"

The song explores how time tests and often strengthens the bonds we share. "Purple Irises" was produced by Scott Hendricks and recorded in Nashville at Smoakstack Studios.

"Purple Irises" comes two days before Stefani will perform at the Super Bowl LVIII TikTok Tailgate before the game between the San Francisco 49ers and the Kansas City Chiefs in Las Vegas. Shelton will join Stefani at Super Bowl LVIII TikTok Tailgate for a debut performance of "Purple Irises."

"Purple Irises is a song that comes from the idea that when you plant something you are planting hope and watching love grow," says Stefani. "Weathering all the different seasons of growth. We are in this together, we planted the seeds together and we are growing together."

The couple have previously shared the mic on the Platinum hits "Nobody But You" and "Happy Anywhere," both of which topped Billboard's Hot Country Songs chart.

"We love this song so much," said Shelton. "It's a song Gwen wrote with a couple of friends of hers, and I fell in love with it the first time I heard it. She knew there was something different about it and asked me to come in and sing with her. My longtime producer, Scott Hendricks, produced it, and Gwen's been wanting to work with him for a long time now, and it's turned into this really cool and different song that can live anywhere."
