We know it's to be expected that our favorite Upper East Siders would have tons of celeb acquaintances, like Olympian Nastia Liukin and socialite Tinsley Mortimer. However, we just didn't expect someone like…wait for it…Nicole Richie to grace Gossip Girl like the rest of 'em! Nicole is in talks to appear on the GG finale, but don't expect her and Blair to be insta-BFFs. "Nicole loves Gossip Girl, and she wants a really beeyatchy, juicy role," a friend of Nicole's tells the NY Daily News. Nothing is set in stone yet, but we'd love to see another headband-flying fight involving Blair -- maybe Nicole will wear some House of Harlow designs for the occasion!
