Natalie Portman smiles on solo outing despite Benjamin Millepied's reported adultery.

The actress was all smiles while out and about in Paris, France, on Saturday,

only days after her husband, Benjamin Millepied, was accused of adultery.

Portman, 41, appeared to be in good spirits while watching a soccer match at the Parc des Princes stadium between Paris Saint-Germain and Clermont Foot 63.

The "No Strings Attached" actress was spotted cheering from the stands in a crisp white button down, jeans, a plaid blazer, black shades, and strong red lipstick.

Portman was also seen laughing with other fans and taking pictures of the game on her phone.

The disclosure happened just two days after it was revealed that her husband, 45, had an affair with a 25-year-old woman.

Page Six reported earlier this week that the couple was fighting to maintain their marriage after

Portman discovered Millepied's affair with a teenage climate activist called Camille Étienne.
