Adam Levine Defends His Bromance With Blake Shelton: 'He's All Mine'

Blake Shelton might be dating Gwen Stefani, but the bromance still continues between him and Adam Levine.

DespiteThe Voice mentors' new romance, Levine says he's still Shelton's favorite on the show. "First of all, he's always been mine, will always be mine, nobody's else's," the rocker joked with ET, "and I don't appreciate that you would ever say he's not all mine."

Stefani doesn't seem to mind Levine being so territorial over Shelton as long as the pair keeps her laughing. "I literally laugh all the time because of these guys," the No Doubt front woman said. "Me and Pharrell [Williams], we have smile headaches when we leave work. We have to do massages, take it down, because it's crazy."

She then told Levine, "[It's] such good chemistry you guys have. We all have."

Stefani joked that all the happiness on set has helped with her workouts. "I don't even have to sit-ups anymore," she quipped. "I just laugh so much."
