Katy Perry has allegedly taken up smoking to relieve the stress of planning her wedding to comedian Russell Brand.
The Hot N Cold singer, who is set to wed Brand in India later this year is now said to be considering hypnotherapy to help quit the habit before she walks up the aisle.
The Mirror claims that Perry reportedly told a 'friend': "I'm stressed out with the wedding and I keep smoking to calm my nerves. I do it even though I know it is really bad for me and I know I need to stop."
"So I'm thinking I am going to have hypnotherapy to help me get over it. I'd never say to kids, 'This is cool'. It's a really bad habit that I need to quit."

Meanwhile, Perry's pal Rihanna is said to be helping with hen party plans while Kanye West and Jay-Z are rumoured to be plotting a 'wild' stag party for Brand.
