The next trend for Centre Court? I CAN'T WAIT"
With the square glasses and floppy hat, it looked like Serena was preparing to make fun of herself as she shot the ad for the racquet brand at the Biltmore Tennis Center.
She tweeted: 'Guess who at a #wilsontennis shoot.'
It appears Russian tennis player Victoria Azarenka, who won the Australian Open Women's Singles this year, was nearby and was overhearing Serena during the shoot.
Ahead of the shoot, Serena was training with her coach Patrick Mouratoglou for the Miami Open.
She tweeted: 'Tough day at the office today @pmouratoglou but I am done and now at a @WilsonTennis shoot.'
