Breaking News: Christina Wayne Quits AMC

In an unexpected twist more likely to be found on the cabler's hit drama series Mad Men, Christina Wayne has quit AMC.

I learned of her departure from the basic cabler today via a source at the network, who spoke to me on condition of anonymity.

Wayne, who was promoted last year to Senior Vice President for Scripted Series and Mini-Series at AMC, has left the network effective as of today. No reason was given for her abrupt exit and it's not immediately clear where Wayne will head next or if she had secured a position elsewhere.

Wayne has served as AMC's head of original scripted programming since 2005 and is responsible for developing the cabler's signature hit dramas Mad Men and Breaking Bad.

UPDATE: AMC has now confirmed my scoop and issued a statement about Wayne's departure. "We're proud of what Christina Wayne has accomplished at AMC during her tenure here," said AMC in a statement, "and thank her for all of her contributions in helping to make AMC home to the best dramas on television."

UPDATE #2: I've now heard from several sources that it appears that Wayne will move to pay cabler Starz.
