Though Stevie Nicks and Lindsey Buckingham have been broken up for nearly 50 years, their mutual antipathy has grown as legendary as their musical output.

Both Buckingham and Nicks have also released reams of solo music. Some fans had theorized that Nicks and Buckingham were teasing a Fleetwood Mac reunion, which would have been the first since the death of vocalist, songwriter and keyboard player Christine McVie in 2022.

Nicks, 77, and Buckingham, 75, took to their Instagram accounts on Thursday, July 17, to share lyrics from “Frozen Love,” the 1973 song they released as the rock duo Buckingham Nicks before Mick Fleetwood heard it and invited them to join his band.
