Meghan Markle cheering on Serena Williams at US Open is #BFFGoals

We've been stargazing at the high profile 2019 US Open spectators all week, but Saturday, September 7 took things to another level. The Duchess of Sussex graced Arthur Ashe Stadium in Queens, New York with her presence, intent on cheering on her best friend Serena Williams in her final match against Bianca Andrescu.

Meghan Markle left baby Archie Harrison and Prince Harry at home in England to return to her homeland, making a fresh-faced and bright-eyed appearance alongside several other stars. Scroll through to see all the best photos of the former actress rooting on Serena!

She jetted across the Atlantic, leaving baby Archie and Prince Harry at home, to watch the US Open final and cheer on her BFF Serena Williams - but sadly it didn't end up quite the way she'd hoped.

The Duchess of Sussex was all smiles as she arrived at the Arthur Ashe Stadium in Queens on Saturday for Serena's final against Bianca Andrescu, but by the end not even a closed-eyed prayer could prevent her good pal from missing out on the prize to Bianca Andreescu.

It was a huge afternoon for Meghan, who, as always, looked flawless, her minimal makeup letting her natural features shine. The former actress opted for a casual chic look, wearing a blue denim J.Crew dress paired with a stylish white cardigan from the same brand, which she wore over her shoulders.

With former Vogue editor Anna Wintour in the crowd just behind her it was quite the fashionista event!

The 38-year-old jetted to the US on Friday, taking the decision to fly commercial and without her husband and son Archie or her team or staff. Of course, as is protocol, the royal was flanked by her security team.
