Jessica Simpson clutched her leopard-print bag leaving dinner with fiancé Eric Johnson and her parents, Tina and Joe, in LA last night. Jessica and Eric are among our most adorable new couples of 2010, though they're not quite your favorite. Still, it's been an incredible year for Jessica, whose fashion empire could reportedly soon cross the $1 billion mark, which would make it the highest-earning celebrity line. It's an impressive feat for Miss Simpson, and she has a lot to look forward to in 2011, including a wedding to Eric, but first up is their first Christmas together. Jessica has been getting in the spirit with her holiday special and album, though she's also ready to take on whatever traditions Eric may have as evidenced by the vegan Thanksgiving feast she made for his family.
