The television network has also clubbed this premiere date with the second season Ray Donovan. Both shows will be embarking on their sophomore year together and for fans of the two, its going to be an exciting night.

While, unlike Ray Donovan, not much has been given away about the plot from season 2 of the Bill-Virginia led study of carnal pleasures, we do have information on a ton of guest stars who will be coming on board.

But one thing we are quite certain of is that Bill Masters will finally cherish, or maybe not, newly acquired fatherhood. We did find out that Masters' wife Libby became pregnant -- although the child is Dr. Ethan Haas' -- toward the finale of the first season.

It was recently revealed that the Masters' household will get a new nanny. Keke Palmer will be playing the part of Coral, caretaker to the Masters' newborn. The 20-year-old actress has featured in films like Animal and Ice Age: Continental Drift before. Audiences will also see her in the upcoming film, A Trip to Bountiful.

Earlier this week, it was also announced that a Breaking Bad alumnus will be joining the show. Betsy Brandt, who is most known for having played the role of Marie Schrader in Breaking Bad, will be playing William's new secretary. Brandt will be filling the rather modestly-sized shoes of the research scientist's former secretary Miss Horchow, played by Margo Martindale -- her guest role lasted for only an episode. William's wife Libby (Caitlin Fitzgerald) also helped as his secretary for part of the first season.

Brandt recently wrapped work as Michael J. Fox's wife on NBC's flailing comedy The Michael J. Fox Show. The series' fate is quite uncertain and rescheduling for seven of its unaired episodes hasn't been confirmed yet.
