Causing A Racquet! Serena Williams Busts A Move Ahead Of Australian Open

It has been coined 'The Happy Slam' for a reason, and Serena Williams' dance moves are an accurate representation of that.

On the eve of the Australian Open --which kicks off at Melbourne Park today -- the 38-year-old appeared relaxed as she broke it down on the court.

Her coach Patrick Mouratoglou posted a video of the tennis great twirling around.

“Working on the last details before the first round of the AO,” Mouratoglou Tweeted.

Williams took to the court for her final practice session before meeting Russia's Anastasia Potapova today, where she broke out into some shimmies and pirouettes while Mouratoglou was having a hit.

Another video of the 23-time Grand Slam Champion dancing around the court was shared over Twitter, with the Tennis account praising her for not taking things too seriously.

"Some days are about practice. Some days are about dance," the caption read.

"It's called balance."

If she plays as well as she dances, Williams is no doubt en-route to another Grand Slam title.
