Russell Brand admits divorce from Katy Perry was the biggest mistake of his life

Russell Brand is said to be “seething with jealously” after his ex-wife Katy Perry was pictured at the Coachella Festival last month with Robert Ackroyd of Florence And The Machine.

This led Russell Brand, 36, to send Katy Perry, 27, a long email admitting that he “gave up” on their marriage too soon.

Russell Brand filed for divorce from Katy Perry in December and cited “irreconcilable differences” as the reason for the split but now it appears being faced with the green-eyed monster has caused him to think things over.

It has been reported that Russell Brand sent the singer an emotional e-mail in which he has asked for a second chance and said ending their 14 month marriage was a “mistake”.

A source close to Russell Brand told 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.”

The source continued: “It’s fair to say that Russell only wishes Katy happiness but perhaps he should have realized just how special his wife was when he was married to her rather than five months later.”

When Russell Brand filed for divorce at the end of last year, it was reported that he did not agree with Katy Perry’s partying lifestyle and he told her to “tone it down”.

Added to the fact that Katy Perry was on a mammoth tour it seems their marriage ultimately paid the cost.

Although Katy Perry has moved on, Russell Brand was spotted with the main woman in his life – his beloved mother Barbara.

The comedian and his mum were spotted lunching in Primrose Hill, North London yesterday.

One day before, Katy Perry tweeted a line from Forrest Gump: “Dear God make me a bird, so I can fly far far far away from here.”
