In 1981 , while remaining a member of Fleetwood Mac , Nicks began her solo career , releasing the album Bella Donna , which topped the Billboard album charts and reached platinum status less than three months after its release , and has since been certified quadruple-platinum . During her solo career , she has had a close working relationship with Tom Petty and the Heartbreakers .
