Katy Perry gave fans a sweet treat last night when she performed a medley of her greatest hits at the premiere of her new 3D movie ‘Katy Perry: Part of Me.’

The pop star shut down Hollywood Boulevard dressed in a festive movie-themed outfit, complete with a film-reel top and popcorn skirt. She kicked off her set, sponsored by Pepsi and Billboard’s ‘Summer Beats’ concert series, with ‘Hot N Cold’ and before launching into renditions of ‘Teenage Dream’ and ‘Last Friday Night (T.G.I.F.).’

Taking things down a notch, Perry addressed the crowd over a mellow beat. “Who’s excited to see the movie? I’m very excited for all of you to see this film,” she said. “I started with this little old song — 2008 — and I never thought that I’d be shutting down Hollywood Boulevard. Thank you for caring. If I could, I would come down there and kiss you all gently … but this next one goes out especially to all of my … girls.”

‘I Kissed a Girl’ and, naturally, ‘Part of Me’ were also included in the live set before Perry got ready for the event at Grauman’s Chinese Theatre. She chose red as her color of the night, wearing head-to-toe Dolce & Gabbana. ‘Katy Perry: Part of Me’ arrives in theaters on July 5.
