WinkBall citizen video reporters were at Manchester Apollo on Tuesday 22nd March for Katy Perry. The American singer-songwriter has risen to fame dramatically since second single 'I Kissed A Girl' was released in 2008, and can now be counted as one of the biggest female artists in the world today. August 2010 saw her second major album 'Teenage Dream' go straight in at number one, as did the singles 'California Gurls', 'Teenage Dream' and 'Firework'. Known also for her colourful wardrobe and recently marrying British comedian Russell Brand, Katy is an icon and one of the most talked-about celebrities and artists in recent times. WinkBall were at her Manchester Apollo show to speak to her fans about the night's proceedings and the lady herself. As the videos below document, they were blown away! The highlight for many came when Katy invited fans to join her onstage at the end. Were you at the Apollo tonight? What was your favourite part of the concert?
