Video: Katy Perry walks the pink carpet for the London premiere of her new film
US pop star Katy Perry got her fans' hearts pounding as she stepped out in Leicester Square for the London premiere of her new concert film Katy Perry: Part of Me.
Hundreds of fans, many of them dressed with coloured wigs and heart-shaped glasses, stood behind the barriers of the pink carpet, which had been decorated with giant milkshakes and lollipop props for Perry's arrival.
Distributor Paramount Pictures and Perry, whose last album Teenage Dream produced such hits as Firework, California Gurls and Last Friday Night (T.G.I.F.), teamed up to promote the first big screen look at Perry's life.
Although Perry counts as one of the most successful female acts around, her fame didn't come overnight.
"When I first moved to Los Angeles at seventeen I really wanted my voice to be heard and my ambition to be realised like then and there. But it never happened until twenty-three. It didn't happen until the timing was right, because looking back if I would have gotten all the success then I may not have been able to handle it. So I always say that God's rejection is God's protection," she said.
The film, which is named after one of her songs, chronicles Perry's religious upbringing, her struggles and pressures on becoming a pop star, her marriage breakup with actor Russell Brand, as well as tour footage.
Katy Perry: Part of Me is released in cinemas on July
