There has been a lot of bitter back-and-forth over social media and song lyrics."There's a situation," Perry said about the feud. "Honestly, it's really like she started it, and it's time for her to finish it. I tried to talk to her about it, and she wouldn't speak to me. I do the right thing but then she writes a song about me. You want to deal with it? Karma."In addition to that, they also addressed the real story behind Perry's famous song 'I Kissed a Girl.' Though the internet believes the song is about a lip-lock with Scarlett Johansson, Perry points out that the song is about a girl that she met when she was 17.Here's the whole segment, and thankfully there's no lip-syncing involved in this karaoke segment (unlike Britney Spears'):
