We caught up with Britney yesterday browsing the latest releases at a music store in the Valley. She even turned her camera on us at one point -- she is Team X17, after all ... Brit then headed to Element later last night, while her one-night paramour "JR" Rotem was at Hyde. Partying separately? What's that mean?

We'll have exclusive pix of Britney last night coming soon -- and if you think all those crotch shots were good, Britney gave us another gift last night that we think might be of interest for you ... stay tuned!
