John Stamos shared the news on Jimmy Kimmel Live on Monday night. "We've been working on this for many, many years," he said.
The new 13-episode series – Fuller House – will be on Netflix next year, and Stamos (who will produce and guest-star) explained that it will start off with a one-hour reunion and then be a spin-off series featuring DJ Tanner (Candace Cameron-Bure) and her three kids, along with her sister Stephanie (Jodie Sweetin) and neighbor Kimmy Gibbler (Andrea Barber).
Stamos said he was hopeful that the other members of the cast would return for the new series, joking with Kimmel, "If we can't get the Olsen twins, we're gonna dress you up."
Netflix confirmed that discussions are ongoing with Mary-Kate and Ashley Olsen, Bob Saget, Dave Coulier and Lori Loughlin about making guest appearances on Fuller House.
The Full House faithful have long hoped for the Tanner family's return to television, and castmates have teased and hinted at the chance in recent months.
A reunion never seemed too far off, considering how often we've seen the former costars together. Many post pictures with one another on social media on the regular, and Stamos recently shared a photo of himself in front of the San Francisco home used for the exterior shots (where fans, inexplicably, did not notice Uncle Jesse coming home).
In January, Stamos, Lori Loughlin, Andrea Barber, Bob Saget and Jodie Sweetin all celebrated show creator Jeff Franklin's birthday – even singing the theme song.
And last July, cast members gathered to celebrate Dave Coulier's wedding.
Still, it's a safe bet that a new season of Full House won't include all of the original cast. (Ashley Olsen and Mary Kate Olsen have been notably absent from social cast reunions.)
"Not everybody would want to do it. Maybe two-thirds of the cast would want to," Saget told PEOPLE in August. "John is such a good guy, and I think he would want it to happen in some way if it could. There's some stuff going on."
Both Stamos and Saget have both spoken about the importance of doing a reboot right and respecting the original series.
"It's such a sweet thing, nobody should mess it up," said Saget, who hasn't been vocal about reunion rumors but has considered the prospect.
"Five years ago, I said, 'Hey, everybody looks pretty good. I kinda still look okay,' " the comedian told PEOPLE. "We should hurry."
