The good news comes a couple of months after the singer expressed an interest in returning to the band full time after appearing with them onstage in London for a few shows.
"McVie has indeed re-joined Fleetwood Mac and we are hoping to make an announcement about a possible tour for the full tilt Macsters some time in 2014," she said.
The 70-year-old rocker first joined the band in 1970 after marrying the group's bassist, John McVie. She stayed with the group for 28 years writing several of their greatest hits, such as "Say You Love Me," "Don't Stop," "You Make Loving Fun," "Hold Me," "Little Lies," and "Everywhere."
After guesting with the band in September 2013 at the O2 arena in London, Mcvie told British newspaper The Guardian, that she does "miss them all" and that "if they were to ask me I would probably be very delighted" to return to the group.
Fleetwood Mac has released one new studio set, 2003's Say You Will and a four-song EP, Extended Play, since McVie's departure in 1998.
