Gwen Stefani's in the hot seat!

The judges of "The Voice" appeared on "Today" this morning, where Matt Lauer really put Gwen on the spot about her new song "Used to Love You" -- asking if fans are misinterpreting the lyrics, or if "it's all right there in front of us." Many have assumed the song -- which includes lyrics about a brutal breakup -- is about her real life split from Gavin Rossdale.

"I’ve never put a record out where I’m actually going through things in real time. This is like, I wrote that song like a couple weeks ago," she said, seemingly confirming it's inspired by the end of her marriage. "[Filming the music video] was all very real. It’s nice to do music and have that support from everybody. I don’t know these people, I feel their energy and love coming back at me and that's really comforting."

All four of them also appeared on "The Tonight Show" on Monday, where Jimmy Fallon challenged them to a game of "Spin the Microphone." The rules of the game are simple: One person spins the microphone and whoever it lands on draws a card with a song from the stack. The player can sing the song or pick someone else to perform it. If they don't know the song, they just have to wing it!

"This is actually the stupidest game I've ever heard of," Shelton mumbled under his breath after Fallon told them the rules.

First up, Fallon spun the microphone and and drew Britney Spears' hit "Oops!...I Did It Again" and gave the song to a less-than-thrilled Levine. "You already look stupid, you haven't even started yet" the country singer told the Maroon 5 frontman as he took the stage.
