Katy Perry has been spotted in London after switching her hair back to flamingo pink.
The 'Teenage Dream' singer only went back to blonde a few days ago, but evidently she got bored of it fairly quickly.
She's in London for the UK leg of her 'California Dreams' tour, and to appear on The X Factor's results show on Sunday. She was a guest judge when Dannii Minogue was on maternity leave last year, and returned to perform her single 'Firework' later in the series.
She's currently gearing up to release her new single 'The One That Got Away'. If it hits number one in the US, it will become a record-breaking sixth chart topper from one LP, a record originally set by Michael Jackson and matched by Perry's 'Last Friday Night' earlier in the year.
Take a look at pink-haired Katy, complete with cat shoes, below.
