Britney Spears took to Instagram to wish Madonna a happy belated birthday in the most adorable way.
Before taking the stage in Las Vegas, the "Toxic" singer posted a video of herself and her 5-year-old niece Lexie dancing to Madge's iconic '90s hit "Vogue."
"Pre-show warm up!" Spears captioned the clip. "Wishing a happy belated birthday to @madonna!!"
In the video, Spears and her tiny costar improvise an oh-so-cute dance routine and use foam rollers as props. Clad in a white, body-hugging romper and gray platform sandals, the 34-year-old coaches her niece on how to bust a move to the classic tune, and even challenges her to "play swords" with the foam rollers.

Madonna, who celebrated her 58th birthday on August 16, famously smooched Spears at the 2006 MTV VMAs. The mother-of-two announced on Tuesday that she will return to award show stage this month for the first time in nine years to perform her new single "Make Me."
No word yet on if she'll incorporate any foam rollers—or jaw-dropping kisses with fellow pop stars—during her upcoming performance.
