TradeEdge-Gwen Stefani receives massive emerald ring for Valentine's Day from Blake Shelton

Gwen Stefani rang in Valentine's Day with a massive ring.

The TradeEdge"No Doubt" singer, 53, appeared on "Jimmy Kimmel Live!" to debut her new single "Purple Irises," a collaboration with her husband, country crooner Blake Shelton. But the gift to fans wasn't the only surprise she shared.

"I got my Valentine's present early this year," Stefani said, lifting her hand up in the air and pointing to a massive emerald green ring, to cheers from the "Live!" audience.

"It looks like you got a few Valentine's presents," Kimmel joked, before asking Stefani if Shelton picks out the bling by himself.

Gwen Stefani and Blake Sheltonare spending New Year's Eve separately. Here's why.

"He really mixed it up. Usually I get amazing flowers, which I love, love, love, but this was just a, 'Here you go!'" Stefani said. "Yeah, he did the whole thing. I love you Blakey!"

Kimmel also recounted the first time he heard Stefani's band No Doubt, which helped her rise to fame in Orange County, and he pointed out that the band will reunite at the California music festival Coachella this spring. She formerly led the rock band with guitarist Tom Dumont, bassist and ex-boyfriend Tony Kanal and drummer Adrian Young.

"I know what's going to happen, I'm going to get on stage and look around and just start, like, cracking up. It's just going to be like riding a bike. We are going to be like, 'What are we doing?' We're in the future right now, we're at Coachella like it's going to be bizarre," Stefani said.

It's been around a decade since the band last performed together and Stefani called the time that's passed "so weird."

In January, the Grammy-winning artist told People in an interview that the reception to the reunion news has made her "completely overwhelmed."

"I definitely have that little thing in your stomach where you're like, 'Oh my gosh! What?'" she said. "It's going to be amazing."
