Katy Perry is still struggling after her breakup with blues guitarist John Mayer over charges of infidelity. John Mayer has a reputation for charming his ex-girlfriends, including Jessica Simpson and Jennifer Aniston, into reuniting. Mayer just hates it when women move on from him.

Katy Perry and John Mayer broke up in February after Mayer cheated on her with Lauren McHale. Sources say Perry is devastated and is looking for ways to help her get over the split. Katy Perry is the latest celebrity reported to be using hypnotherapy. Katy is a firm believer in alternative therapies Sources say Russell Brand's ex-wife is "retraining" her brain to prevent taking her ex-boyfriend John Mayer back.

Perry doesn't want to Mayer attractive anymore.

A source told British magazine Grazia, "Katy was devastated when they broke up. But she 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."

This isn't the first time Katy Perry has used hypnosis, she reportedly used the treatment after her marriage to comedian Russell Brand ended in 2011.

Perry wants to erase Mayer from her life. First she moved all of his belongings out of her place.

The source told Britain's Grazia magazine "Katy has been really hurt by John and she doesn't want him worming his way back in. This time she's determined to erase him from her life. 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 the past."

The source says "[Katy]really wants a fresh start and she is well on her way to putting her relationship with John firmly in the past. 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 doesn't want to find him attractive anymore."

Perry doesn't just use hypnotherapy for herself. Katy Perry once credited telepathic hypnosis for helping her tame the wild British comedian Russell Brand.

Back in 2011, she told Star magazine "I was trying to make him tell me that he wanted to marry me telepathically. Every night we looked into each other's eyes and I was thinking, 'Please ask me, please ask me.' Then, when we finally talked about the idea of getting married, he admitted he was thinking the same - he'd been trying to tell me that I was the woman he wanted to marry by communicating it with his eyes. So all the time we'd been sending each other subliminal messages!"

It's is surprising Perry didn't use her hypnotic magic on Mayer, she brags about her prowess in her latest hit "Dark Horse." The lyrics are below:

I knew you were

 You were gonna come to me

 And here you are

 But you better choose carefully

'Cause I, I'm capable of anything

 Of anything and everything

 Make me your Aphrodite

 Make me your one and only

 But don't make me your enemy, your enemy, your enemy

 So you wanna play with magic

 Boy, you should know what you're falling for

 Baby do you dare to do this?

 Cause I'm coming at you like a dark horse

 Are you ready for, ready for

 A perfect storm, perfect storm

 Cause once you're mine, once you're mine

 There's no going back

 Mark my words

 This love will make you levitate

 Like a bird

 Like a bird without a cage

 But down to earth

 If you choose to walk away, don't walk away

 It's in the palm of your hand now baby

 It's a yes or no, no maybe

 So just be sure before you give it all to me

 All to me, give it all to me

 So you wanna play with magic

 Boy, you should know what you're falling for

 Baby do you dare to do this?

 Cause I'm coming at you like a dark horse

 Are you ready for, ready for

 A perfect storm, perfect storm

 Cause once you're mine, once you're mine (love trippin')

 There's no going back

 So you wanna play with magic

 Boy, you should know what you're falling for (you should know)

 Baby do you dare to do this?

 Cause I'm coming at you like a dark horse (like a dark horse)

 Are you ready for, ready for (ready for)

 A perfect storm, perfect storm (a perfect storm)

 Cause once you're mine, once you're mine (mine)

 There's no going back
