The pop princess turned 32 yesterday and was given a fun little video made by her dancers Pammy Chu and Lianna Blackburn.
And only E! News has the Flipagram vid to show you.
The footage features a montage of Spears' dancers, crew members and management team doing a faux hand-slapping move from her "Work, Bitch" video to a sample of the lyrics, "Work it out."
And guess who is the last person in the sequence? Brit's dad, Jamie Spears, in a sideways baseball cap.
