After all his hard work on Clash of the Choirs, Nick Lachey naturally needed a vacation and, lucky for him, Vanessa was free to go along. They arrived back at LAX on Sunday after a trip to Costa Rica, where they were awkwardly staying in a hotel next door to Pete Wentz and Ashlee Simpson. Jessica and Tony had apparently planned to be on the trip, too, but ended up in Mexico instead. Ha, that might have been bad news. That said, these two couples should be ready to bump into each other at some point, since Nick helped organize the Super Skins Celebrity Golf Classic, a golf tournament in conjunction with the Super Bowl, and Tony may find himself there for the big game.
