The big news from this new preview for season four of Girls: Marnie will be doing lots of singing this season. Meanwhile, the show will continue to feature an impressive amount of cameos, including Ana Gasteyer (as Shosh’s mom!), Zachary Quinto, Marc Maron, and Gillian Jacobs. Will Hannah and Adam stay together? Will Jessa figure herself out? Will Marnie learn that no one wants to hear her sing? Seems like a no for the last one.
