Ever wonder how Katy Perry feels about ex-boyfriend, Gym Class Heroes frontman Travis McCoy? Wonder no longer! Katy is starting to let loose about Travis in some of her shows. Evidently after Travis penned a little diss for Ms. Perry on his website last year saying, ''We fight every night, now that’s not kosher. I reminisce with bliss of when we was closer. And wake up to be greeted by an argument again, You act like you’re 10.'' Katy hadn’t said much until a recent show at Los Angeles’ Wiltern Theatre, where she shot back, ''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.''
Hmm, so it doesn’t exactly sound like this was a pleasant parting of the ways. We reported that Katy was recently seen with Benji Madden over the Valentine’s holiday weekend so it sounds like she’s having fun and getting past Travis despite her denials that she and Benji aren't dating. Hopefully whoever she picks will be a little less hot and cold.
