CORRECTION: PEOPLE.com's Feb. 2 report that Katy Perry told an audience at her show in Los Angeles not to date the lead singer from Gym Class Heroes (Travis McCoy) was incorrect. The quote was based on erroneous reporting. People.com regrets the error.

Instead, Perry told the audience at the Wiltern Theatre in Los Angeles on Saturday night: "Girls if you feel me, if you've ever dated the lead singer from Death Cab For Cutie ... it's not like that, I'm not engaged ... this one goes out to him," she said referring to Ben Gibbard, who is engaged to Perry's look-alike Zooey Deschanel. Perry added later, just before singing her song, "Hot N Cold," "To all of the my upcoming relationships – one foot in, one foot out. He wants the milk but he never wants to buy the cow."

The incorrect quote stated: "Girls, if you have ever dated a boy – specifically the lead singer from Gym Class Heroes – don't do it! Boys should have a heart. You know what I mean girls? Boys just want the milk, but they don't want to buy the cow."
