Britney Spears and her new boyfriend, David Lucado, wore matching outfits when they caught a flight out of LA on Friday for a weekend trip to Las Vegas. While in Sin City, Britney and David had dinner with a group of friends at the Meatball Spot and reportedly caught Shania Twain's Still the One show at Caesars Palace. The couple also stopped by Cirque du Soleil's One Drop show, where Britney and David took a photo for her Facebook page. The trip was just a quick one, as the couple jetted out of Vegas on Sunday. Britney and David have been inseparable since their Valentine's Day date earlier this year, but they made their romance official when Britney and David held hands in public ahead of their flight last week.
