Haim Had A Total ⚡️Legendary⚡️ Moment Onstage

Stevie Nicks gifted them a magical scarf.

Fans at the Foo Fighters' L.A. Forum show were totally surprised on Monday night when Dave Grohl and co. brought out some special guests to create one legendary supergroup.

The Foos invited Fleetwood Mac singer Stevie Nicks and Haim onstage to perform Tom Petty and Nicks' 1981 song "Stop Draggin' My Heart Around."

Haim acted as backup singers of some sort, swaying around while Grohl and Nicks traded verses. They also played Fleetwood Mac's 1977 hit "Gold Dust Woman."

After they show, it seemed like they were in disbelief of what just happened. Understandable.

"Died on stage tonight with @StevieNicks and @foofighters ?," they wrote on Twitter.

And apparently, Stevie gave them a "magical scarf" to wear onstage.

"When @stevienicksofficial GIVES YOU YOUR OWN MAGICAL SCARF TO WEAR ON STAGE BEFORE YOURE ABOUT TO SING GOLD DUST WOMEN WITH HER AND THE @foofighters what is LIFE. ????"

Pure magic.
