Last week, "Parenthood" revealed a shocking spoiler in its sixth and final season in a video teaser.

The preview video, which aired during the 66th Emmy Awards, confirmed that Amber is indeed pregnant with Ryan's baby.

As many TV fans can recall, Amber walked into a convenience store and purchased a pregnancy test in the Season 5 finale of "Parenthood," leaving viewers wondering whether or not she got pregnant after she and Ryan rekindled their old flame.

The Season 6 promo basically let the cat out of the bag by showing Amber in a doctor's office looking at a sonogram.

"Parenthood" executive producer Jason Katims also dropped a spoiler about Amber, telling TVLine that Ryan, who is played by Matt Lauria, will return in Episode 3 of the upcoming season.

During a recent interview with TV Guide, the EP also revealed that a cohesive and inclusive storyline will run throughout the entire sixth season.

"We wanted to have a strong central story that would bring everybody together, that would touch everybody in the show," he said. "I felt like the one thing that was sort of similar was [Kristina's] breast cancer story line in Season 4, but I think that this one has the weight of that, but will actually even be more impactful on the entire cast."

In addition, he teased that the main storyline will reflect a "changing of the guard" within the Braverman family hierarchy.

"One of the things that I feel this show is about is about the generations in a family," he said. "We want to do a story that shows what winds up happening in life when our four adult siblings get to a certain point where they're getting to be middle-aged and they're getting to that point where the tables are starting to turn a little bit. We hinted at it in the last episode of last season of Adam sort of becoming the patriarch of the family."

Season 6 of "Parenthood" is slated to begin on Sept. 25 on NBC.
