Katy Perry turns to hypnotherapy

Katy Perry is "retraining" her brain to get over her ex-boyfriend John Mayer.

They split in February, for reasons of infidelity from his side. Katy has turned to hypnotherapy to try and help herself move on.

"Katy was devastated when they broke up", a source told British magazine Grazia.

"But Katy is a firm believer in alternative therapies and she wants to wipe him from her life for good, so she decided to see a hypnotherapist. She wants to retrain her brain to prevent John coming back".

She used the treatment three years ago, after her marriage to comedian Russell Brand fell apart.

Katy, 29 years old, and John split on a couple of occasions during their two year relationship, but she took him back each time. However she is determined to stick to her latest decision.

"They had talked about marriage and she seemed to think he was a changed man, so she is beyond gutted," the source continued. "[But] she doesn't want to find him attractive anymore".

John is 36 years old and he is renowned for charming his exes into getting back together with him! One of them is also Jessica Simpson and Jennifer Aniston. Katy's refusal to give him yet another chance will not sit well with the musician.

"He hates women moving on from him but this time she's determined to completely erase him from her life," the insider added. "Her first step was to get him to move all of his belongings out of her home. Katy wants a fresh start and she is well on her way to putting her relationship with John firmly in her past".
