A tearful Britney Spears fan named Chris Crocker posted a passionate video called Leave Britney Alone! on YouTube after the pop star’s disastrous MTV Awards performance. Crocker’s video has become an instant YouTube hit and has gotten about 4 million views.

In it, Crocker defends Britney’s widely-criticized performance at the MTV Video Music Awards on Sunday, in which the troubled pop star appeared out of time and out of shape while miming the words to her new song “Gimme More.” It reminded me of Ashlee Simpson’s SNL un-synced disaster.

Crocker berates the media for their treatment of Britney since the awards show and says fans should be thankful she decided to perform. Here’s a transcript of his rant:

“How f**king dare anyone out there make fun of Britney after all she’s been through. She went through a divorce, she had two kids … and now she’s going through a custody battle. All you people care about is readers and making money off of her.

She’s a human. She hasn’t performed on stage in years. Her song is called Gimme More for a reason – because all you people want is more, more, more, more, more … leave her alone. You’re lucky she even performed for you bastards. Leave Britney alone … please.”

Crocker, who has posted other YouTube videos about Britney Spears, said on the Howard Stern Sirius satellite radio show yesterday that he was “not acting” and was “really crying.”
