Listen to Stevie Nicks on iHeartRadio

(Yahoo!) - Fleetwood Mac's Stevie Nicks was on the set of "Glee" for only two days in 2011 but created a deep bond with the cast during her brief time there. That bond grew even stronger after Cory Monteith passed away from a drug overdose in July.

"I made a real serious connection with all of them," she said. "And when Cory died I was devastated and I wrote a letter to the cast and I wrote to Lea and I sent her a bunch of stuff and I really tried to help."

The singer has a new documentary, "In Your Dreams," in stores now and revealed to "omg! Insider" correspondent Keltie Knight on Wednesday that she did her best to help Lea Michele get through the tough time because she, too, had recently lost a loved one due to an overdose.

"I had lost a godson to an overdose of Xanax and alcohol at a frat party at the end of 2011. That was heavily on my mind," Stevie revealed. "It's all an accident, a bad accident."
