In September, Christine McVie joined her former bandmates in Fleetwood Mac on stage in London.  They played Don't Stop, a song that she wrote and one of the band's biggest hits.

Now, it sounds like the reunion will stick.

On stage Saturday night, Mick Fleetwood told the crowd, "This is the worst kept secret there is, but Christine McVie will be rejoining Fleetwood Mac!"

McVie left the band 1998.  She released a solo album in 2004.
