Serena Williams Shows Off Belly Button Piercing

She is known for her confidence on and off the tennis court.

And on Friday night, Serena Williams remained true to form as she strutted her stuff at the Australian Open Players Party at the Club Sofitel Lounge in Melbourne.

Despite being relatively dressed down for the occasion, the 34-year-old athlete exuded poise as she flaunted her midriff, complete with bellybutton piercing, in a black crop top matched with a pair of basic black leggings.
