Stevie Nicks' very busy autumn just got even busier.

She was already set to join Fleetwood Mac on the road for a round of tour dates that will bring Christine McVie back to the fold for the first time in years -- and in addition to the band's upcoming new album, she's got a solo disc in the works. But as it turns out, she somehow had a little more room left in her schedule.

Nicks, who appeared on 'American Horror Story: Coven' last season, will return to TV this fall as one of the advisers for NBC's singing competition series 'The Voice.' The network reports that Nicks is joining Adam Levine's team to offer various bits of advice to contestants, stepping into a role that's previously been filled by stars such as Cher, Taylor Swift, and Coldplay's Chris Martin.

The new season, the show's seventh, also finds Gwen Stefani and Pharrell Williams joining the coaching ranks, replacing the departed Usher and Shakira. According to NBC, 'The Voice' is scheduled to return to the airwaves on Sept. 22; there's no word on specific airdates for Nicks, although her appearances will presumably need to be worked around her touring commitments to Fleetwood Mac, which begin Sept. 30.
