“‘Unconditionally’ was influenced by my boyfriend and also really influenced by Africa,” Katy recently told EW.

She added, “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. 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.”

FYI: Katy is wearing Dolce&Gabbana.
