Los Angeles: Singer Britney Spears has revealed that she has "never" met "Bad blood" hitmaker Taylor Swift. The 34-year-old star has admitted she would rather sit next to singer Katy Perry over Swift because she claims they haven't met one another before, although her meeting with the "Rise" singer in the past was only brief, femalefirst.co.uk. During a radio interview about the person she would prefer to be accompanied on a 24-hour flight with, Spears said: "I don't know! I don't know, that's hard. They're both so cool, I don't know. "I've briefly met Katy Perry at the 'Smurfs' movie premiere. Maybe because I've met Katy Perry, I would say Taylor Swift, because I've never met her before," she added.
