Illeana Douglas is out. Sheila Kelley is in.

A few days after Gossip Girl announced that Douglas was unavailable to play the role of Lily's sister this spring, The CW has tracked down her replacement.

Kelley will take on the character - portrayed by Krysten Ritter on Season 2's flashback episode - later in the season. The actress is best known for recurring on Lost as Zoe.

Do you see a resemblance to Lily? What do you think of this casting move?
