Katy Perry and John Mayer are getting super serious, but as anyone who's followed their tumultuous relationship knows, they've had quite a few ups and downs -- including quite a few splits -- in between. Thankfully, though, those are behind them ... and they even inspired Perry's smash hit, 'Roar.'

Perry gave some insight on their relationship in an interview with the BBC (via 3News) in which she revealed that the drama was partly her own fault.

"'Roar' is a song I wrote as I was a little bit upset," she confessed. "I found myself having a break with my boyfriend, who I loved very much and it really hurt my heart. I said to myself, 'I need to see what is going on with me and make sure I'm all good,'" she said.

As a result, lyrics like "I got the eye of the tiger," "I am a champion and you're gonna hear me roar" were born and set to music that may or may not have been appropriated from Sara Bareilles' 'Brave.' Or, you know, the lyrics were possibly appropriated from other songs like, well, 'Eye of the Tiger,' 'We Are the Champions' and 'I Am Woman.'

She added, "When you break up with someone it's easy to say they are crazy and think it's all them, but, honestly, maybe there is 50 percent responsibility on your behalf," Perry advised. "It was just time for me to be honest with myself."

Honesty's the best policy, KP!
