Singer Katy Perry made good on her promise.
At her Wells Fargo show Tuesday night, Perry told fans she was going to be at the Philadelphia Museum of Art after the show. Fans say the pop star — donned in a silk, pizza-printed onesie with a hood — was dropped off at the top of the museum's steps and ran down them, "Rocky" style, and met with hundreds of fans who showed up.
Perry met with some of them, taking selfies before being whisked away by security guards.
Instagram user "nourawoodward" posted a montage of photos Perry took with fans on Tuesday night.
Perry tweeted this last night, showing that she makes good on her word.
