Mad Men begins its fifth season on March 25 -- and a few spoilers about the hit advertising agency drama have already emerged.
At the end of the last series, Don Draper (Jon Hamm) proposed to his twentysomething secretary just days after they first slept together.
As the new season kicks off on AMC, the two-hour premiere includes a surprise birthday party for Don - a surprise he doesn't welcome.
Pete (Vincent Kartheiser) has a new home and a baby with his wife, Trudy, but, as usual, he feels undervalued at the office. But what about the baby that Joan (Christina Hendricks) was carrying? Did she have it, or terminate the pregnancy over worries that her husband isn't the father?
TV bosses say Mad Men will continue for at least two more seasons, fulfilling creator Matthew Weiner's original vision of covering the whole of the Sixties.
