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.
The singer is currently in Las Vegas rehearsing for Piece of Me, her residency show launching at Planet Hollywood on Dec. 27.
"There's a lot of different, interesting aspects to the show and a lot of moments where the audience feels like they're in the show with us," Spears told Ryan Seacrest during a recent iHeart radio album preview for Britney Jean. "A lot of special effects like that and it's the most dancing I've ever done."
She told E! News in September that Vegas will be her "second home" and not her primary residence.
"It seemed like the ideal job to me because I felt like when I was on tour, I'm in a different bed every night," Spears said. "It felt kind of ideal to be set in one place."
