Jessica Simpson jessicaadam.jpgLast night, X17 spies spotted Simpson at Maroon 5 frontman Adam Levine's Halloween House party. After the party, photogs caught the busty songstress driving thru Wendy's for a late night snack. Hmmm, what could the pair, who famously hooked up right after (?) she separated from Nick, have done at that party to make her so hungry???
