Los Angeles, CA -- Stevie Nicks thinks she probably would have married Lindsey Buckingham and had a child if it weren't for Fleetwood Mac. Nicks tells "Oprah's Master Class" everyone in Fleetwood Mac knew the band was bigger than each separate person's problems -- even the breakups of couples within the band. She says Buckingham always blamed Fleetwood Mac for his breakup with Nicks. She says had they not joined the band, they were still young enough to have had a family and pursue music, "but destiny did not take us that way." "Oprah's Master Class" airs Sunday on the Oprah Winfrey Network.
