Taylor Momsen Out…Kaylee Defer In! Gossip Girl’s New Mystery Girl

There’s going to be a new face on the CW’s “Gossip Girl” later this season according to reports. Kaylee Defer is joining the cast and while everyone is being pretty tight lipped about what the stunning 24 year old will be playing on the show, there’s no doubt it could take some twist and turns with the introduction of her as a new character, espeically since Taylor Momsen (Jenny Humphrey) has taken an “indefinite hiatus.”

If Kaylee looks familiar, it’s because she’s been around the TV having roles on “How I Met Your Mother,” “The Ghost Whisperer” and “The War at Home.”

New episodes of “Gossip Girl” head back to the CW on January 24th.
