Katy Perry may just be bitter, but she still thinks it's her duty to warn other women not to get married!
While Katy was partying at London's Mahiki nightclub over the weekend, she reportedly crashed Laura Cooney's bachelorette party and told her: 'Don't do it.'
Laura claims: 'She ran up to me, saying 'Don't do it! Don't get married!' Laura says Katy was very sweet and after they chatted for about ten minutes, Katy wished her luck and gave her congratulations.
