Katy Perry will be treating fans with a special live performance tonight (June 26) at the Los Angeles premiere of her new movie, ‘Katy Perry: Part of Me.’

The 27-year-old will be singing on Hollywood Boulevard just before hitting the red carpet at Grauman’s Chinese Theatre for the unveiling of her 3D film, MTV reports.

The performance is part of Pepsi and Billboard’s ‘Summer Beats’ concert series, which kicks off today. Fans who can’t be there in person need not worry, though. According to the singer, the red carpet arrivals and live show will be streamed on Pepsi’s Twitter page at 6PM PT.

Perry, who is known for her bold style choices, also revealed her plans to wow the crowd yet again. “My costume for tomorrow’s premiere performance is so yolo,” she tweeted on Monday.

‘Katy Perry: Part of Me’ offers fans a glimpse into the pop star’s life. The film includes home movie footage, live concert performances and scenes involving her ex-husband, Russell Brand.

Perry told MTV News, “There’s some scenes that I know people will screenshot and be like, ‘Oh, she looks like a fat cow with zits.’ But I put those in there because that’s a part of me, that’s reality, and I’m OK with that now.”
