Mary-Kate Olsen’s return to acting bit the dust after The CW drove a stake through the heart of a proposed television drama that would have featured the former Full House actress as a bloodsucking vampire.

The mini-mogul, now 23, had been slated to play glamorous teen socialite Schuyler van Allen on The CW Network’s adaptation of the young adult literary series Blue Bloods, according to GLOBE. Blue Bloods creator Melissa de la Cruz selected the “cool and vunerable” Mary-Kate for the role. However, Mary-Kate’s big vamp debut fell through when the network dumped the pilot in favor of another show about immortal high schools — The Vampire Diaries.

Word is CW bosses dumped Mary-Kate’s starring vehicle after deeming the show “too similar to Gossip Girl.”
