LONDON - Pop singer Pink regrets staging a circus themed show for her ongoing world tour because she has been plagued by comparisons to Britney Spears.

The ‘So what’ hitmaker is taking her ‘Funhouse’ world tour to the US this summer and has been bombarded by critics accusing her of copying Spears who launched her own ‘Circus’ tour in the country in March.

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

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

‘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,’ said the singer.
