BritBrit is looking good!

The popstar had a photo shoot with famed photographer Jeff Lipsky -- and we are liking what we are seeing!

The "Womanizer" singer gave her Facebook fans a sneak peek at the celeb snapper's pic of her in her undies. Hot damn -- look at that mom of two!

Along with the pic, the 32-year-old wrote, "Amazing amazing shoot with Jeff Lipsky today! Been working hard this summer!"

Is the old Britney back? Doubtful -- but we do love that this photo reminds of us the iconic "Hit Me Baby One More" time album (sans pants of course)!
