In a new interview with Rolling Stone, the singer/songwriter reveals she's taking another break from the band and believes another MAC album will be a huge waste of time and money.

"I don’t think there's any reason to spend a year and an amazing amount of money on a record that, even if it has great things, isn’t going to sell.

"I don’t think we’ll do another record. If the music business were different, I might feel different. What we do is go on the road, do a ton of shows and make lots of money. We have a lot of fun. Making a record isn’t all that much fun."

But she has no qualms about bandmates Lindsey Buckingham and Christine MCVie turning what was planned as a Fleetwood Mac album into a separate project.

"I will be back with them at the end of the year for, I think, another tour," Nicks said. "I just needed my two years off. Until then, I wish them the best in whatever they do."

Buckingham and MCVie will release an album of duets, tentatively titled Buckingham MCVie, in May (17). The set will feature contributions from Fleetwood MAC bandmates John MCVie and Mick Fleetwood.

Meanwhile, the group's classic 1987 album Tango in the Night is set for a 30th anniversary re-release at the end of March (17). A deluxe and expanded reissue will feature 13 previously unheard recordings, including an alternate version of Christine MCVie's ballad Mystified, and a demo of Lindsey Buckingham's Down Endless Street and Ricky, while the deluxe edition also offers an album of 12-inch mixes, including dub versions of Seven Wonders and Everywhere.

The band will also headline the Classic East and Classic West festivals in New York and Los Angeles this summer (17).

Fleetwood MAC's last album, Say You Will, was released in 2003.
