(Cover) - EN Showbiz - Katy Perry says she is often so busy, she needs three hands.

The 26-year-old megastar has had a busy time recently following her marriage to husband Russell Brand and the release of her third studio album, Teenage Dream, last year.

The star is now planning the fine details of her world tour which will see her cover North America, Europe, Japan and Australia. The hectic nature of the event means Katy often struggles to cope.

If I could have another hand that would be really helpful! she joked to Company magazine.

Katy hopes to take inspiration from her stint on the Vans Warped tour in 2008. The singer appeared alongside a variety of acts at the summer festival with great success. Katy confirms the event has made her what she is today, and as a result will fuel her future performances on tour.

I learnt so much on the Vans Warped tour because I dont think the crowd was there to see me, so I really have to win them over every single show. That was cool and I was happy to do that because fighting for their attention helped me get where I am today, she said, before revealing what fans can expect from her concerts.

The show is a big production, but there will be wonderful moments where I can strip it down to just me and my guitar. Yes, people will be able to dance and maybe they will be able to cry, but in a lovely way. And I dont want to ruin any surprise but, I might be changing over 20 times in one show. (C) Cover Media
