Jessica Simpson stuck close to her fiancé, Eric Johnson, yesterday when they arrived at LAX. The duo were fresh off a weekend mingling with some of his old friends at his 10-year college reunion at Yale. The gathering brought out Eric's classmate Cash Warren, who attended with his wife, Jessica Alba, and their daughter Honor. The two Jessicas got decked out to see the sights of New Haven, CT, which included a playing field for Simpson and her former football star man Eric. Their trip to Connecticut came after a few days in NYC. Jessica and Eric were in the Big Apple with her sister Ashlee, starting to work on their upcoming fashion line for tweens.
