Eva Longoria is standing by her man.

Longoria, 32, showed up at L.A.’s Staples Center, where Tony Parker’s team, the San Antonio Spurs, faced off against the L.A. Lakers Thursday.

Parker, 25, sprained his ankle and sat out of the game while Longoria mingled with pals Mario Lopez and Ryan Seacrest. (She drove to the game with pal Sheryl Crow.)

Though the Spurs lost, Longoria and Parker — who deny a model’s claim that Parker cheated on her — were all smiles as they dined with friends at Hollywood sushi restaurant Katsuya in Hollywood later that night (see photo, left). (The model released alleged text messages from Parker yesterday.)

It wasn’t the pair’s only sighting Thursday. That morning, Parker popped by the L.A. set of a L’Oreal commercial his wife is shooting with Heather Locklear.

“Tony went straight into Eva’s trailer,” an onlooker tells Usmagazine.com. “She was already on set when he arrived but he waited for her to come back.

“She came back with a big smile on her face and acted as if nothing could possibly be wrong,” the source adds. “At the end of the day, they came out holding hands and seemed very much together.”
