Nick Lachey arrived at LAX yesterday without his trusty airport buddy Vanessa, which might help explain his long face. Awww, poor Nick. He was off to NYC in his beloved USC hat to talk about his Super Bowl Skins Golf Classic, Online Auction and Party to help raise money for the Jimmy Johnson Foundation all Super Bowl weekend long. Nick said, "What a great opportunity -- so many people are at the Super Bowl that weekend -- what a great opportunity to ... raise some great money for a good cause." Gotta give Nick extra golf claps (get it? Har, har) for using one of his favorite sporting events to help give back.
