Katy Perry was too overcome with emotion to tweet after watching Fleetwood Mac live.
The star and her boyfriend John Mayer had been to see the band perform in Las Vegas, where Stevie Nicks dedicated famous song Landslide to Katy and John.
After the show, John logged on to Katy's Twitter account to tell her fans about the evening.
"John here. Katy can't write because she's getting over Stevie Nicks dedicating Landslide to us at the Fleetwood Mac concert. Unforgettable.
"While I'm at it I have a couple things I'd like to get off my-oh, she's motioning for the phone back. Gotta go!! 'JM (sic)" he posted to her 49million followers.
Fleetwood Mac took to the stage at the MGM Grand Garden Arena in Las Vegas in their first performance since founding band member John McVie announced he was to undergo treatment for cancer.
Katy has made no secret of her love and admiration for Stevie in the past.
She revealed earlier this year that Katy's track Roar was her favourite song of the moment, which prompted the 29-year-old to respond with an equally glowing compliment.
"She is a beautiful woman," Katy told SiriusXM. "She just has so many little nuggets of wisdom and sees straight through my soul.
"And she's very kind, and a sweet woman. I'm so honoured that she would make time for me. But I like hearing what people who have gone before me have to say about all this stuff."
