Miranda Lambert will serve as a mentor on NBC’s The Voice upcoming sixth season, but she’s not advising hubby Blake Shelton‘s team. Instead, Miranda is helping out Blake’s rival, Shakira, during the battle round rehearsals.

Miranda tells Access Hollywood that Blake is a little nervous about her new role helping Shakira’s team, and he’s got good reason to be shaking in his boots. Miranda says, “I have to go home and investigate, and then I’ll call [Shakira]: ‘”I found this out. You need to do this.’”

The Voice‘s sixth season kicks off February 24 on NBC.
