The "Desperate Housewives" star and hubby were out and about last night.

Following rumors of infidelity in their marriage, EVA LONGORIA and TONY PARKER made a show of unity -- first at a photo shoot for the "Desperate Housewives" star, then at a Los Angeles Lakers game -- it was reported by People magazine.

As ET detailed yesterday, a French model is claiming that she had an affair with the NBA star since his marriage to Eva last July.

"They held hands and smiled," an observer at the photo session told the magazine.

Following the game, Eva and Tony dined at Katsuya, a sushi restaurant in Hollywood, with friends. Then the couple faced the waiting photographers outside -- holding hands.
