It's well known that the Williams sisters host an annual dance-squad competition, but that doesn't mean they limit their performances to that second-most wonderful time of year. Witness Venus Williams' delivery of a lip-sync meets dance take on Britney Spears' insufferably titled "I'm A Slave 4 U."

That's the Queen Vee, sporting a wide-brimmed sun hat and a slit-to-the-hilt maxi dress, rocking a mic and playing to the camera. "Get it, Vee!" shouts one live observer—who sounds sort of like Serena. Either way, no one could agree more.

Since 1999, parallels have played out in the career arcs of Venus and Britney, respectively. *Yahoo* has the goods on that, and Venus recently made headlines in noting that, if she's healthy, she fully intends to play in the next Olympic Games in Tokyo in 2020.
