There’s nothing worse for a woman than a wardrobe malfunction that you don’t know about, and Katy Perry is the latest victim. It’s bad enough having your bottom on show if you’re not a celebrity but if you are a celeb someone will have a camera and there will be photographic evidence. I guess if you’re wearing a tiny mini skirt like Katy was on a recent night out in London it’s bound to happen! She was also wearing fish net tights, black biker boots and a biker jacket. She left a club in Soho in London, ignored all the photographers and climbed into a car. Maybe she felt quite liberated? The other interesting thing that happened that night when she was leaving the club was who she left the club with … She was recently rumoured to have hooked up romantically with the guitarist from Florence and the Machine, Robert Ackroyd, but they had supposedly gone their opposite ways. They were both desperately trying not to get photographed together – does that mean they’re back on? Last month it was thought that Russell Brand was jealous after seeing photos of Katy and Robert together and it allegedly gave him a nudge to send Katy an e-mail to say that he ‘gave up’ on their marriage too soon? Surely that’s the type of conversation you should at least have on the phone. Their divorce is due to go through next month. Jessie J has got her mind set on getting in the studio with Katy Perry stating collaboration between them will definitely happen. They performed at a gig recently together and Jessie said "We hung out a bit. I went round and saw her and we sat in her dressing room for a bit. I definitely think me and Katy one day will work together." Nothing formal has been set in stone and Jessie J gets annoyed how things can be blown out of proportion. She said one minute you’re chatting about it and the next people think you’re going to write a whole album together. Jessie is still enjoying a new boost of fame following a mentoring stint on The Voice UK
