The Gossip Girl spinoff is gearing up.

The show will be launched as an episode of the original series in episode 24, when we will travel to Los Angeles for a look back at the life of Lily Rhodes (Kelly Rutherford) when she was a lost young soul slumming around the Valley.

According to sources, the spinoff-setup episode of Gossip Girl shoots in Los Angeles in mid-March, meaning there are just two short months to cast these roles:

Lily, who is being touted as a teenage version of the Lily van der Woodsen we all know and love. Gorgeous and privileged, Lily has a bit of a rebellious streak that doesn't sit well with her parents. When she's kicked out of her prestigious boarding school, Lily is forced to relocate to her older sister's home in the Valley!

Owen, a 19-year-old hottie from the wrong side of the tracks. Possible love interest for Lily perhaps? What will Rufus think?!

Carol Rhodes, Lily's adorable big sister, is a free-spirited actress waiting for her big break! She's in her early 20s and always seems to be making bad decisions - the wrong men, the wrong career choices... you name it! Her screwups will definitely add a fun, comic element to the show, according to the producers.

Lily's dad, Rick Rhodes, is a handsome and charming music executive always looking for the next big thing. By the looks of it, Rick will have no trouble fitting in on the West Coast: Hot young girlfriend? Check. Supertanned and toned? Check!

There's even going to be a young version of Cece, Lily's mom, who we're already familiar with. Little has changed from the version of Cece we know from Gossip Girl - the same overly critical, stuffy and cold New Yorker, just younger.

Do you have anyone you think would be great in these roles?

Regarding Lily, we've put together a revised version of our poll from two weeks ago, using some of your suggestions! Which of these actresses do you think should play Lily - or should a new, unknown starlet be cast as the lead character?

Who should play young Lily?
