In-trend 'circus' theme irks Pink

Pink regrets staging a circus-themed show for her ongoing world tour - because she's been plagued by comparisons to Britney Spears.

The 'So What 'hitmaker is taking her 'Funhouse' world tour Stateside this summer and has been bombarded by critics accusing her of copying Spears - who launched her own 'Circus' tour in the US in March.

Both singers based their themes on the title of their latest albums and feature high-flying dancers, acrobats and wild acts in their stage shows.

But Pink, whose album debuted last year, just weeks before Spears' release, insists she was oblivious to the trend.

She said: "Had I known that certain other people were going to base their latest thing about circus things, I probably would have went into another direction. I was six months before that and didn't really understand that it was a trend that was happening. I'm pretty out of the loop."
