Serena is well established as one of her sport's all-time greats and winning the title for the third time in the last four years - she missed the 2017 tournament due to her pregnancy - would only enhance her standing.
Meghan Markle has apparently hit all the right notes in her transition into the royal world, after marrying Prince Harry in a once-in-a-generation ceremony just two months ago, according to her close friend Priyanka Chopra.
It will mark the pair's first official engagement together without their husbands.
And Meghan has always admired sports legend Serena, explaining to Vogue while her friend was pregnant: "She will be an fantastic mum, The very best, because she is so attuned to balancing strength and sensitivity".
Earlier on Wednesday, she opted for a gray dress with a draped skirt by Roland Mouret. She paired that look with matching black pumps and a black clutch. "I look forward to it", she said. However, one obvious missing link in an otherwise flawless tour de couture was the glaring lack of Irish designers incorporated anywhere into her wardrobe.
Before long, Meghan had made another style swap into what might have been her most daring (and fabulous) outfit of the whole trip - a black pantsuit! Now if only all fathers-in-law were that cool.
