Charlie in charge? Armed with a taste of the Manhattan socialite lifestyle, blank checks courtesy of Grandma Rhodes, and Georgina’s phone number on a crumbled napkin, this Serena-in-training-wheels is bound to cause a Gossip Girl blast or two.

There’s just one teeny catch: Cousin Charlie is really a poser named Ivy hired by Lily’s sis Carol. Hmm, lying, fraud, deceit…sounds like Ivy’s part of the family, after all.

And now that Georgina’s found herself a new baby daddy who makes bank, you can bet she’ll ditch playtime with Milo to make Ivy her shiny new toy. To think Serena thought a stolen dress was the best her little cousin could do.

Do you think Charlie will team up with the mighty Georgina? Or will she make another (successful?) pass at one of Serena’s past flames? Watch these sparks fly when Gossip Girl returns Sept 26 on The CW at 8/7c
