Listen to Fleetwood Mac on iHeartRadio

Christine McVie says her ex-husband and former Fleetwood Mac bandmate is doing well in his cancer battle. 

She tells the UK's "Guardian" that John McVie's "prognosis looks good," and that they believe he'll be "up and running again in a couple of months." 

John's health prompted Fleetwood Mac to scrap a planned tour of Australia and New Zealand.  However, the group will be back on stage later this month.  Fleetwood Mac has a December 30th performance slated for Las Vegas. 

And while there's been talk of Christine rejoining the group, there are no indications that she'll be performing with the band at this show.
