As hoped, Megan Mullally and Cheryl Hines have signed on to join the cast of In the Motherhood, ABC's broadcast adaptation of the popular online series starring Chelsea Handler, Leah Remini and Jenny McCarthy, and chronicling "the hilarious ups and downs of motherhood."

While Mullally (a winner of two Emmys for her work on Will & Grace) and Hines (twice nominated for Curb Your Enthusiasm) represent the only official casting to date, there has been speculation that from the Internet original, Handler might cross over to round out the trio.
