Pop beauty Katy Perry has opened up about a new song that features on her upcoming album, 'Prism', and revealed that it was inspired by her boyfriend, John Mayer. 

The song, entitled 'Unconditionally', surfaced earlier this week and she has now confessed that her love with Mayer acted as inspiration for the lyrics along with her recent trip to Africa for charity:

"'Unconditionally' was influenced by my boyfriend and also really influenced by Africa. I went to Madagascar and did a UNICEF trip that changed my life and gave me this song. It’s just a simple message about loving someone and accepting them and kind of driving at you don’t have to be so self-conscious, you don’t have to fear, because essentially, everybody has their stuff."

Perry added: "Nobody comes stuff-free. Everybody has their things and you’re never going to be perfect, and accepting that and understanding that, especially in a relationship, it makes room for a real, genuine kind of love."
