Britney Hits the Elevator for Madonna Concert Video

Here's the scoop, bitch.

Cameras started to roll today on the video that Britney Spears is making for Madonna's upcoming Sticky & Sweet tour, which, sources tell E! News, will be the opening video for each show.

The "Are you ready to rumble?!" video, if you will.

The shoot took place today at the Lot in West Hollywood, the former site of Warner Hollywood, United Artists and the Samuel Goldwyn Studios.

An on-set source said that Britney arrived at around 9 a.m. and was holed up in her dressing room by 9:30. The "Toxic" singer didn't start shooting her scenes until noon and was still on the set a few hours later.

According to our insiders, the planned "short movie" will take place inside an elevator, where seven cameras will be strategically placed to capture the magic. The scene-by-scene breakdown goes like this:

Britney, partially disguised by a gray hoodie, walks into the elevator. As she starts traveling upward, she seems particularly nervous and anxious. The popster starts pacing back and forth. Then she progresses to kicking and smacking the walls, all frantic-like. She screams into one of the cameras. Then she starts climbing the wall, pulls down her hood and, into another camera, says:

"It's Britney, bitch."

Well, at least she shouldn't have trouble remembering her lines.

Strains of Madonna's "Human Nature" were also heard playing during some scenes and Britney could be seen mouthing the words.

We're told that the 26-year-old mother of two acted "very professional" throughout and, a day after the shoot was postponed due to technical difficulties, everything seemed to be back on schedule.

But apparently even veteran performers need some time to shake the dust off if they've been away for awhile. Britney was also "really nervous and kept biting her nails—but she’s doing a good job," our source said, adding, "She's being incredibly sweet!"

Meanwhile, despite rumors that Madonna was going to wing her way west for a quick set visit, the Material Girl stayed put in New York today. According to a witness privy to her comings and goings, she went to her studio this morning and then returned to her Manhattan apartment.

Where, if Madonna weren't used to the current tabloid climate, she would have bolted the door, drawn the shades and pulled the covers over her head.

But she probably just ate lunch.
