POWER COUPLE: A sun-kissed Cameron Diaz dazzled guests at a cocktail at Elie Saab’s Paris home on Wednesday night – marking the wrap-up of couture week – accompanied by her towering beau, New York Yankees star Alex Rodriguez. “I love Paris,” enthused Rodriguez, adding that earlier in the day he and Diaz had gone to see the Jean-Michel Basquiat exhibition at the city’s Musée d’Art Moderne. “His work is just amazing.” The third baseman looks forward to the start of baseball season, on April 1. “So I have been training pretty hard,” he said. Jokester Diaz dished out surfing tips, meanwhile. “You have to paddle, paddle hard,” she laughed. The actress has just finished shooting the comedy “Bad Teacher,” which also stars Justin Timberlake. Numero editor-in-chief Babette Djian nipped into the party briefly, in between shooting with Karl Lagerfeld. Meanwhile, Middle Eastern songstress Elissa entertained guests with some of her hits and then danced the night away with other revelers.
