From the looks of it, Williams is gearing up for a partnership with luxury watch brand Audemars Piguet, which would be added to her long list of existing brand partnerships with the likes of Chase, Berlei, Nike and Wilson, among others.

The all time tennis great surprised fans last month when she announced that she was "20 weeks" pregnant on her Snapchat story. She's expecting her first child with fiancé Alexis Ohanian, the millionaire Reddit co-founder. She later revealed in an interview with Gayle King that her massive pregnancy reveal was a complete accident -- she actually just meant to send the Snapchat to a private group of friends instead of her public story.

"You know how social media is, you press the wrong button and..." she hilariously revealed.

Williams and Ohanian made their first post-announcement public appearance last week at the 2017 Met Gala, where Williams showed off her baby bump in a stunning green Versace gown.
