Gwen Stefani and Adam Levine performed Maroon 5's 'My Heart Is Open' at the 2015 Grammy Awards and they totally proved that, as much as we love them individually, they're a total musical power couple.
Gwen's made her way back into the spotlight after taking one of the famous spinning chairs on NBC's "The Voice." Now she's hoping to make her way back into the spotlight as a solo artist with her new song "Baby Don't Lie."
