Katy Perry has revealed that she ditched alcohol and went on a spiritual cleanse after she broke up with husband Russell Brand.

The two celebrities married in 2010 before splitting just over a year later.

Speaking on Alan Carr's Chatty Man show, the pop songstress said that she was being chased by "negative thoughts" after the break-up.

However, she went tee-total for three months and swapped her busy showbiz life for a period of hiking and meditation.

Perry said: "You know I did a lot of different things, I surrounded myself with my good friends, I did this whole cleanse where I didn’t have any of the alcohol for three months – that was devastating – I did vitamins and supplements, and hikes and meditation and prayer. 

"But I think at the end of it all, as much as the things I did, I think there was something cosmically happening that was looking out for me in some ways, but I was putting my best positive foot forward."
