Nicks revealed that Fleetwood Mac will definitely regroup for a tour while appearing on CBS This Morning on Wednesday (July 11).
"[A reunion is] the plan," the singer declared, adding: "Because that's what we do. I do my thing, and Lindsey [Buckingham is] out doing his thing."
Nicks's comments come just two months after drummer Mick Fleetwood suggested that another Fleetwood Mac tour was unlikely.
Asked on CBS This Morning if all of Fleetwood Mac's current band members are on board for a regrouping, Nicks replied: "Oh, yeah!"
The group released their last studio record Say You Will in 2003.
Fleetwood Mac are also the subject of a new tribute album Just Tell Me That You Want Me, which features MGMT, Lykke Li and The Kills.
Just Tell Me That You Want Me: A Tribute To Fleetwood Mac is released on August 13 in the UK and one day later in the US.
