New pop princess Katy Perry has wowed her fans in Germany as part of her world tour, taking in Paris, London and Sydney.

The I Kissed a Girl singer said her sudden rise to fame has created a hectic schedule but she is enjoying every minute of it.

"I am just getting used to having a real career and a new job. I have the opportunity now and I'm definitely seizing the moment. I know that sounds cheesy but it is true."

The 23-year-old's songs have proved controversial but Perry has said her music is all about having fun and telling people what she really thinks.

"Sometimes I have used my relationships in the past as my therapy couch where I don't know how to verbalise it to a person. So I put it in a song, and sing it to them and it's the only way the little problems are fixed."
