Salma Hayek hit the Balenciaga fashion show in Paris Tuesday morning with a very special guest. Her escort? Ex-fiancé Francois-Henri Pinault, the owner of the fashion house and father of her one-year-old daughter Valentina Paloma.
"[They were] very friendly together, looking happy," said one attendee. "They weren't holding hands but were definitely side by side."
The couple's public outing comes just weeks after they were spotted together in Los Angeles. It also caps a low-key week in Paris during which Hayek, 42, and Pinault, 46, have spent a great deal of time together privately. (Sources tell PEOPLE Hayek was introducing her daughter to Pinault's French relatives.)
