Look for Justin Timberlake at La Carreta, a Mexican restaurant in Hammond, La., where he's filming The Open Road. The singer, who brought girlfriend Jessica Biel there, recently ordered the $100 margarita (with three shots of Don Julio 1942 tequila). When someone does, "everyone in the restaurant sings," says owner Saul Rubio. "We tried to get him [to wear] the big sombrero, but he didn't want to."
PARIS & BENJI IN VEGAS
The fastest moving couple in Hollywood hit Las Vegas to celebrate Benji Madden's b-day (he and brother Joel turn 29 on March 11). Madden and Paris Hilton hit Pure Nightclub March 7, where she showed off a "BM" ring on her engagement finger, saying coyly earlier, "It's just a ring." The next night, they shared a cake at LAX, and Hilton took the mic to announce, "I want to say Happy Birthday to Benji. I love you!"
