What did you get up to this past weekend? If your name is Britney Spears, then you spent Saturday and Sunday shooting the video for the current #1 single in the country, “Hold It Against Me.” Jonas Åkerlund, who was behind the lens for such classic clips as Madonna’s “Ray Of Light” and Christina Aguilera’s “Beautiful,” is directing Brit’s vid. “Day 1 of the HIAM shoot with Jonas. Such an incredible experience. I think this will be one of the best videos I have ever done,” Spears tweeted on Saturday. Yesterday she added, “Day 2 is a wrap! #HIAM video coming soon.” This photo accompanied her tweet, and it appears to show her surrounded by dozens of microphones.
