Still stinging from her split with Russell Brand, soon-to-be divorcee Katy Perry warned a bachelorette on Saturday night, "Don't do it! Don't get married." Bachelorette Laura Cooney was sporting a white dress and tiara when the blue-haired pop star approached her at London dance club Mahiki.

"She ran up to me, saying: 'Don't do it. Don't get married!" Cooney explained to the UK's Daily Mirror. "I said, 'I thought you'd say that.' She suddenly caught herself and said, 'No, really ... congratulations.'"
