Has fleetwood mac ever played with the band heart? ?

Looking for a heart song on the live verisons they have played with Carrie Underwood and Gretchen wilson performing songs such as barrcuda, crazy on you and straight on (as well as a few of there songs) so I wondered if they have ever performed with (the best rock band of all time) fleetwood mac but google is google and can never give real results so I figured I'd ask here and see if anyone's ever read anything or even seen them show up while at one of there concerts.
