That's big of him! Katy Perry's ex Travis McCoy goes down pretty hard (allegedly) in the pop star's latest track "Circle The Drain," but McCoy kept his cool when we caught up with him at LAX last night...

"I wish her the best," said Travis without any sarcasm. Haven't heard the lyrics? Here are some:

"You fall asleep during foreplay/ 'Cause the pills you take/ Are more your forte/ I'm not sticking around to watch you go down/ Wanna be your lover/ Not your f***ing mother/ Can't be your savior/ I don't have the power/ I'm not gonna stay and watch you circle the drain." Burn!
