Britney Spears' manager has explained the two Britneys in her new video.
Speaking to MTV her manager Larry Rudolph said: 'There are really two different Britneys. There's a public Britney and there's a private Britney, and they are very different.
'Maybe the world doesn't really know that, maybe those of us who do know her really well understand that, but there really are two different Britneys.
'Maybe at some times the two Britneys are at odds with each other; most of the time they're not.'
