Katy Perry's had an eventual few days in Las Vegas. The pop star attended the premiere night of Britney Spears' Vegas residency at Planet Hollywood, and on Dec. 30 she attended a Fleetwood Mac concert with boyfriend John Mayer.
The couple got a special surprise that left Perry, 29, speechless. Mayer, 36, hijacked his chart-topping girlfriend's official Twitter account to share the news.
"John here. Katy can't write because she's getting over Stevie Nicks dedicating Landslide to us at the Fleetwood Mac concert. Unforgettable," he wrote.
Perry recently told Us Weekly that she and Nicks are "buds."
Nicks, 65, has also been busy for the last few days. On Dec. 27, she officiated the wedding of Vanessa Carlton and singer and guitarist John McCauley.
Perry and Mayer have been dating for more than a year, and after an on-again-off-again start to their relationship, the couple has remained together recently, debuting their duet "Who You Love" and the accompanying music video earlier this month.
