Britney Spears isn't holding anything back from her fans from the set of her "Hold It Against Me" video.

The star, 29, Tweeted the first-ever shot from the sexy video shoot in L.A. late Sunday.

In the blurry shot, the superstar (seen through a video camera's frame) gives a sultry look over her shoulder as she's surrounded by a halo of microphones.

On Saturday, after the first day of shooting, Spears Tweeted: "Such an incredible experience. I think this will be one of the best videos I have ever done."

The director is Swedish wunderkind Jonas Akurland -- who has helmed such classic videos as Lady Gaga and Beyonce's "Telephone," Madonna's "Ray of Light" and more.

Last week, Spears enjoyed the stellar news that "Hold It Against Me" debuted in the top spot on Billboard's Hot 100 Singles chart -- shattering first-day sales records on iTunes.

"Seriously, I have the best fans ever," Spears Tweeted. "I love you all so much!"
