Katie Perry has revealed that she would be moving away from pop music when she reaches her thirties and her follow-up to 'Prism' would be more of a acoustic guitar album.
The 28-year-old, whose latest single 'Roar' was a huge success, said that she looks forward to ditching her winning pop formula for a more mature sound, Metro.co.uk reported.
Perry said that she will probably turn into more of a Joni Mitchell.
The 'I Kissed a Girl' hitmaker told Billboard that this is how she started when she was first discovered by songwriter/producer, Glen Ballard, and got her first record deal.
