Fans are abuzz after Stevie Nicks and Lindsey Buckingham, the former Fleetwood Mac bandmates who were once romantically involved, posted lyrics from “Frozen Love.” Days later, a billboard popped up in Los Angeles teasing a new project and fueling rumors of a possible reunion.

The album’s songs, including “Dreams” and “Go Your Own Way” were fueled by the breakup of the Buckingham-Nicks relationship as well as the simultaneous dissolution of the marriage between keyboardist Christine McVie and her husband, bass player John McVie.

Stevie Nicks and Lindsey Buckingham have sparked reunion rumors with seemingly coordinated Instagram posts. The musicians famously dated in the late ’60s and made the 1973 studio album “Buckingham Nicks.” Shortly after, Nicks, 77, and Buckingham, 75, joined Fleetwood Mac.
