Paris Hilton and boyfriend Benji Madden attended the In Touch Weekly party at Social Hollywood last night, where one of X17's spies says the heiress was super-nice and gracious to all her fans!

Benji, however, kept his sunglasses on the entire night (classy), never smiled, and looked "polite" at best, while Paris smiled and chatted with anyone she came into contact with!

Think Benji's just shy or does he shun the spotlight?

In either case, if he's gonna stay with Paris long term, he'd better get used to being the center of attention!
