An aspiring actress and known New York City fashionista, Stella Maeve, has signed on for an upcoming part on Gossip Girl, according to OK! magazine.

Stella Maeve will play the character of Emma, the teenage daughter of a Yale University alum, who Blair Waldorf gets to "babysit" for the evening.

Why Blair is babysitting anyone is another question, but it sounds like a fun storyline with a lot of comedic potential. Here's a picture of Stella ...

From what we hear, Emma's been doing her homework on her new socialite "nanny" by reading up on Gossip Girl (the blog), and comes up with some interesting ideas on how she wants to be entertained by Blair Waldorf.

Can't wait to see what develops with this!
