'Parenthood' Season 4 renewed: Lauren Graham and Peter Krause remain Bravermans for 15 episodes

Get ready for Bill O'Reilly to be absolutely scandalized, folks. "Parenthood" is coming back to NBC! You'll want to stock up on tissues, as NBC has officially alerted the cast and crew of "Parenthood" that they'll be returning to the set to shoot Season 4.

The bad news is that the drama has only been picked up for 15 episodes beginning in Fall 2012, but there's always the chance that NBC may extend the order, as they did this past season.

The regular cast will return, including Lauren Graham, Peter Krause, and Erika Christensen. Additionally, Jason Ritter -- who once again has been cast in another pilot this season -- has promised to return to his role as Mark, if only to wrap up some storylines... like that whole engagement-to-Sarah thing.

We can't wait to see what's next for our Bravermans. And whether or not Sarah and Amber open a bakery. Or an inn. Or whatever.

The pickup was first reported by TVLine.
