During an interview with BBC Radio 1 on Wednesday, Britney Spears shut down the rumor that she might be collaborating with Justin Bieber. When asked about the collaboration by radio host Scott Mills, Spears laughed and said, "There's no truth to that at all." While it may not be happening in the near future, fans can still dream! Britney did say that she's met Bieber before though and she said, "He?s very unassuming. He?s a very nice, kind boy."
