A rare joint appearance between Bella and Gigi Hadid was witnessed at the US Open.

A group of friends and Bella's boyfriend accompanied the Hadids to the US Open.

Kin Euphorics partner wore casual athleisure. An khaki skirt paired with a white track jacket. 

Chunky sneakers with brown-and-tan socks. Sunglasses completed the look.

Gigi went colorful. Simon Miller wore a spaghetti-strap tank with slouchy pants.

An air Jordan 2 and Louis Vuitton clutch completed the monochromatic look.

Serena Williams beat Anett Kontaveit 7-6 (4), 2-6, 6-2 with her sisters watching.

I am my mom's brain and Bella is her heart when it comes to family and world matters. 

A mix. At the dinner table, Bella will be emotional as I pull up charts and infographics. 

Easy for her. One of my dad's stories is goofy, but always ties to a Palestinian saying."
