Britney Spears BSPEARSINSIDE120107_13.jpgBy now you've probably seen the pix and the XCLUSIVE video from Brit's birthday celebration, but what about what happened after she went back to the Four Seasons? Well, aside from hanging out on her balcony with Paris, some over-zealous photogs (NOT OURS) got a little too close to the birthday girl and were pepper-sprayed by security! No one was seriously injured, but man, that sure looked like it burned!

We've got even more pix and video from Brit's birthday coming soon!
