The couple are celebrating the occasion in the appropriately romantic French Riviera, where Longoria is in town as the L’Oreal ambassador at the 70th annual Cannes International Film Festival.
PEOPLE caught up with the Desperate Housewives star, 42, at the festival, and she opened up about married life with Baston. “I’m not a fan of marriage; I like being married to him,” she said.
“I never thought I would get married again. It’s him, he makes it all worth it,” said Longoria. (The actress had previously been married twice.)
To celebrate their anniversary, Longoria said, “We went to dinner last night here in Cannes.” But Baston had a few extra tricks up his sleeve for the evening.

“My husband’s full of surprises,” Longoria explained. “You would think I would catch on that something’s happening, but I don’t, ever.”
For their anniversary, she said, “I wanted to stay in the room and play backgammon, because I was winning … and he was like, ‘No we should go to dinner.’ ”
When they got to the restaurant, Longoria explained, “He surprised me at dinner with a beautiful gift and a song and a singer it was just amazing.”
