This star’s look is a summer grand slam.

Natalie Portman looked tennis-ready in a straw sun hat and floral dress as she attended the 2023 French Open in Paris on Wednesday amid the cheating rumors surrounding her husband, Benjamin Millepied.

The “Black Swan” star, 42, stepped out in a swingy, short dress by French designer Claudie Pierlot, wearing a tan, purple and yellow wrap-front style from the label’s spring/summer 2021 collection.

Although her exact cotton poplin dress is no longer available, the style is still offered in a bright blue shade ($240, originally $300).

She kept the French designer theme going with a Christian Dior sun hat, wearing the label’s sold-out $890 large-brim straw style with a ribbon band.

The Dior ambassador shaded her eyes with a pair of black cat-eye sunglasses ($515) from Ahlem and donned black peep-toe espadrille wedges and a black Dior handbag ($3,900).

Her sparkling 4-carat engagement ring was also on display following rumors that ballet dancer Millepied — who married the Academy Award winner in 2012 — cheated on her with a 25-year-old woman named Camille Étienne.

For more Page Six Style …

“They have not split and are trying to work things out,” a source told Page Six last week. “Ben is doing everything he can to get Natalie to forgive him. He loves her and their family.”

The star certainly looked unbothered as she took in the match between Coco Gauff and  Iga Świątek Wednesday, beaming as she cheered on the American and Polish tennis stars.

Personal matters aside, Portman is certainly serving up some beautiful summer looks.
