'Life Unexpected' star Britt Robertson is staying in The CW family as a lead on the network's new pilot, 'Secret Circle.'

According to Entertainment Weekly, Robertson's casting in the drama series is in second position, behind 'Life Unexpected,' though it's not specified what part she'll play. The CW has not officially made a final decision on the fate of 'Life Unexpected,' but with a "complete series" DVD set being released soon, all signs point to its cancellation.

'Secret Circle' is based on L.J. Smith's novels about a young woman who moves to a new town and finds out she's a witch. Not only is she a witch, but she's part of a secret coven and is the key to the battle between good and evil.
