Kevin & Britney Mix Work, Romance in Vegas MONDAY JULY 31, 2006 01:50PM EST Federline and Spears in February Photo by: Danny Moloshok / AP Kevin Federline traveled to Las Vegas for work to shoot his "Lose Control" video but, with wife Britney Spears in tow, managed to find time for fun. On Thursday night, Federline, 28, Spears, 24, their 10-month-old son, Sean Preston, and seven friends hit the Sin City restaurant Tao at the Venetian, where Mom and Dad dined on Buddha Chicken and Kobe Sirloin and baby Sean enjoyed mashed carrots, spinach and asparagus prepared just for him by head chef Josh Thomsen, a source tells PEOPLE. On Saturday, Federline, who will perform "Lose Control" at the Teen Choice Awards on Aug. 20, filmed the video for the song at Pure Nightclub at Caesars Palace. Once the video had wrapped at around 10:30 p.m., Pure opened to clubgoers and Federline and his crew stayed to celebrate. Spears, who is expecting the couple's second child this fall, stopped by shortly after midnight and received a hug and plenty of attention from her husband, an observer tells PEOPLE. After half an hour of canoodling, Spears headed to Tao at the Venetian with a few girlfriends and watched the dance floor from a private perch, while at Pure, Federline took center stage, emceeing from the DJ booth. And he knew how to work the crowd "Lose Control" was played four times, and by the final spin, the crowd was chanting along.
