Proving that it's not over until the fat lady sings, or in this case, until all technological avenues have been exhausted, Russell Brand has reportedly bashed out an e mail to Katy Perry begging her to take him back.

In it, Russell describes their speedy divorce as the 'biggest mistake of his life' and admits that he 'gave up on their marriage too soon.' The revelation comes after Katy Perry was snapped in a clinch with Robert Ackroyd of Florence and The Machine. Yes, there is a machine.

A source tells Grazia magazine: 'Word has it Russell was "seething with jealousy" when he saw pictures of her with Rob. He apparently feels he gave up on their relationship too easily.'

'It's fair to say that Russell only wishes Katy happiness but perhaps he should have realised just how special his wife was when he was married to her rather than five months later.'

Katy continued the game of cyber cat and mouse by tweeting: 'Dear God make me a bird, so I can fly far far far away from here.'

Cryptic.
