Lindsey Buckingham BANNED This A-Lister From Joining Fleetwood Mac

Sheryl Crow reportedly was set to join pal Stevie Nicks and her band, Fleetwood Mac, but member Lindsey Buckingham nixed it. “I wish I could’ve,” confesses Sheryl. “I felt like if there was gonna be bad blood when I joined, that perhaps maybe I shouldn’t. I didn’t want to upset something that was already beautiful. I would still love to do it. I’m putting that out there.” What’s Lindsey’s gripe?
