Actress and NYC fashionista Stella Maeve, (she's a big fan of Big Apple-based designer Tiffany Koury) has joined the cast of Gossip Girl, the TV Fanatic can exclusively reveal.

 

Stella plays Emma, the young teen daughter of a Yale University alum, who Blair gets to "babysit" for the evening. Does Miss Waldorf need a side gig?

 

Emma's been doing her homework on her socialite nanny by reading up on Gossip Girl, and has some interesting ideas on how she wants to be entertained by Blair.

 

I hope none of those escapades include Lord Marcus. Blair will go far to get greenlit straight to the Ivy League, but I think she'd  kill first to protect her would-be throne.

 

Gossip Girl airs Mondays at 8 p.m. on The CW.
