Onlinereports thatThe Vampire DiariesstarElizabeth Blackmorehas signed on for a guest-starring role inSeason 11ofSupernatural, which will lead into a regular recurring role inSeason 12. It isn’t known exactly when the actress will make her debut on the show quite yet.

The report reveals thatElizabeth Blackmoreis playing Lady Toni Bevill, a “mysterious visitor from across the pond,” who has quite a bit in common with Sam (Jared Padalecki) andDean Winchester(Jensen Ackles). Lady Toni Bevill will also return as a recurring character for an unspecified amount of episodes inSeason 12. Since her character onThe Vampire Diaries, Valerie, is still alive, the report speculates that the actress may end up pulling double duty on both shows, but that hasn’t been confirmed.

The CW renewed all 11 of its shows last month, ordering new seasons ofJane the Virgin(Season 3),Crazy Ex-Girlfriend(Season 2),The Flash(Season 3),iZombie(Season 3),Arrow(Season 5),Supernatural(Season 12),DC’s Legends of Tomorrow(Season 2),The 100(Season 4),The Vampire Diaries(Season 8),The Originals(Season 4) andReign(Season 4). The network hasn’t announcedpremiere datesyet, but it seems likely thatSupernatural, the network’s longest-running show, will stay put in its Wednesday 9 PM ET time slot.

Sam and Deanhave spent their lives on the road, battling every kind of supernatural threat. Over the years, after countless bloody adventures, they have faced everything from the yellow-eyed demon that killed their mother to vampires, ghosts, shapeshifters, angels and fallen gods. With the help of allies - both human and supernatural - they’ve discovered that every victory comes with a price. Supernatural is produced by Wonderland Sound and Vision in association with Warner Bros. Television, with executive producersJeremy Carver, Robert Singer and Philip Sgriccia.Eric Kripkecreated theTV seriesand serves as executive consultant, along withMcG.

Elizabeth BlackmorejoinedThe Vampire DiariesinSeason 7, portraying a heretic named Valerie. Since she isn’t a series regular, it’s possible that she could continue to recur onThe Vampire Diarieswhile also portraying Lady Toni Bevill onSupernaturalat the same time. The actress has a two-episode arc in the upcoming season of AMC’sTurn: Washington’s Spies, which debuts later this month. What do you think about this new addition to theSupernaturalcast?
