Perry revealed: "There’s nothing better than an impromptu dance party with my friends. My track Last Friday Night (T.G.I.F.) is a song about debauchery because I had one of those nights in Santa Barbara. We went out to this place called Wildcat and got crazy,”
Despite drawing from her own experiences in the tune, the 26-year old was keen to point out that the saucy threesome mentioned in the track didn't actually happen.
Katy admitted: “We had a couple of beers and danced until we died, then brought the party back to the hotel room."
She added: "Most of that song is actual truth, apart from the ménage à trois... unfortunately! But, yes, streaking in the park, that’s what we did, so we had to write a song about it the next day!”
