Katy Perry Slams Drug Addict Ex In New Song

They say the best revenge you can take on your ex is to live well, but, for Katy Perry, the greatest revenge is evidently to write a song about your former drug addict ex and then publicize it to your financial benefit.

One of Katy's songs on her upcoming album, Teenage Dream, is all about Travis McCoy, whom Katy dated on and off through-out 2008. Although she is now happily engaged to Russell Brand, himself an admitted former heroin addict, Katy would like everyone to know how messed up Travis was during their relationship.

"It's kind of like my You Oughta Know, Alanis Morissette moment," she told Billboard Magazine recently, referring to Alanis' angst-ridden song that is rumored to be about her ex, Dave Coulier.

According to the New York Post, some of the lyrics to Circle the Drain include:

"Thought I was the exception/ I could rewrite your addiction/ You could have been the greatest/ But you'd rather get wasted/ You fall asleep during foreplay/ 'Cause the pills you take are more your forté/ I'm not sticking around to watch you go down/ Wanna be your lover/ Not your [bleep]ing mother."

Travis, who has since cleaned up from his drug-addict days as the lead singer of the Gym Class Heroes, is now a sober, solo artist and has acknowledged that he went to rehab and had been addicted to pharmaceutical drugs since he was 15 years old.

His addiction clearly had a profound effect on his relationship with Katy, and according to a source, Travis was once thrown out of Madison Square Garden, where Katy was performing at the Z100 Jingle Ball, for being too messed up.

"She came offstage, and he was gone," said the source. The two broke up shortly after that. Katy Perry Takes Vow of Celibacy

Word to Russell Brand, don't cheat on Katy or mess up your relationship, or there will likely be a song about you too!
