You're gonna hear them roar. Ever since Taylor Swift told Rolling Stone that she'd written a song, "Bad Blood," about her rivalry with a fellow female artist, speculation has been rampant about who the artist in question is. Some have mentioned Miley Cyrus as a possibility, but an overwhelming number of fans think the track is a dig at Katy Perry — and sources tell Us Weekly those fans are right.
Perry herself fueled the speculation when she tweeted about an unnamed mean girl on Tuesday, Sept. 9, the day after Rolling Stone's story went live. "Watch out for the Regina George in sheep's clothing..." the "Roar" songstress, 29, wrote, referring to Rachel McAdams' character in Mean Girls.
