Ben Savage, Danielle Fishel join 'Girl Meets World'

(CNN) -- Ben Savage and Danielle Fishel are officially parents - on TV, that is. The rumored "Girl Meets World" sequel series now has both original "Boy Meets World" cast members on board to return to their roles of Cory Matthews and Topanga Lawrence, who in the new series are parents of the protagonist, a teen girl.

Savage, 32, confirmed via Twitter Monday that the series is "officially happening," and Fishel, 31, backed him up on Tumblr.

She explained that in order to get the sequel series off the ground, there were plenty of conversations with those who were integral to the casting and creation of "Boy Meets World," which ran for seven seasons from 1993 to 2000 ( the re-runs of are probably airing somewhere right now).

The '90s hit has a devoted fanbase, and Fishel assured them that co-creator Michael Jacobs and her co-stars Savage, Rider Strong and Will Friedle feel just as strongly as she does about creating a new show that holds up to the original.

"he seven wonderful years we spent making 'BMW' ... were among the most warm, hilarious, insightful, educational years of my life and I wouldn't trade them for the world," Fishel said. "Another thing I wouldn't trade for anything is the integrity and the heart with which 'BMW' was made. I promise with the entirety of my heart that we will make 'GMW' with the same honesty, innocence, and intelligence that you learned to expect from 'BMW.'"

She doesn't know how many of the original cast members would return for "Girl Meets World" or how often they'd appear if they did sign up, but she does emphasize that "Girl Meets World" is a new show.

"It isn't 'BMW' brought back to life," Fishel wrote. "It will have familiar faces, familiar themes and familiar messages. It will also have new faces, new themes and new messages. 'BMW' never spoke down to the audience and we are going to do our best to never do that with 'GMW.' But please keep in mind that this will be episode one, of season one, of a brand new show. We started at the same place with 'BMW' but we evolved and we evolved quickly. For those of you who knew and loved 'BMW,' please allow this show to evolve as well."

According to TVLine, which first broke the news of a sequel series, "Girl Meets World" picks up more than 10 years after the conclusion of "Boy Meets World," with Cory and Topanga now married and parents of a 13-year-old named Riley, a role which has yet to be cast. The pilot is in the very early stages of development under Jacobs' guidance.
