Stevie Nicks has confirmed that Christine McVie will join Fleetwood Mac on two of their London shows and she will rehearse with them in Ireland.
Speaking to BBC Radio 4 Nicks said, "She is going to come and do a song on the second two shows, I think it will probably be Don't Stop. I don't know for sure but she's coming to Ireland to rehearse with us."
McVie joined Fleetwood Mac in 1970 after marrying bassist John McVie. The couple had divorced by the end of the Rumours tour in 1979.
Her last performance with Fleetwood Mac was in 1998 and she appeared on their 2003 album Say You Will.
They kick off their European tour in Dublin on Friday September 20th.
