The "Glee" cast received condolences over star Cory Monteith's death in July from an unexpected source -- Fleetwood Mac's Stevie Nicks.
The singer told Britain's “Stella” magazine that her own experiences with drug addiction led her to write a note to the cast:
"I said, 'Forgive me if I'm stepping into your personal space. I lost my godson to an overdose last year -- he died at a fraternity party -- so I do understand how shocking that is.' When what happened to Cory happened, I was just sick for days. Honestly, just sick. (Drugs are) just so prevalent. It's everywhere. It's worse than when we were young."
Nicks does have a history with "Glee;" she worked with the cast during a 2011 episode that features several songs from Fleetwood Mac's "Rumours" album.
Monteith died July 13 in a Vancouver hotel room from an overdose of heroin and alcohol.
Fleetwood Mac, meanwhile, is preparing for a European tour that begins Friday (September 20) in Dublin, Ireland, with former member Christine McVie planning to guest with the band during a couple of the shows.
