Perry overcome by Nicks' dedication
Katy Perry was left overcome with emotion after Stevie Nicks dedicated a song to her and John Mayer.
The couple had gone to see Fleetwood Mac at the MGM Grand Garden Arena in Las Vegas, and John had to tweet on Katy's behalf after Stevie made the tribute to them on stage.
John tweeted to Katy's 49 million followers on her official account: "John here. Katy can't write because she's getting over Stevie Nicks dedicating Landslide to us at the Fleetwood Mac concert. Unforgettable."
The singer then teased: "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."
The couple, who have been dating on-and-off since August 2012, recently released a duet together, Who You Love.
