Fishel admits she and Savage agonised over the decision to reprise their roles as childhood sweethearts in new show Girl Meets World as they didn't want to tarnish the legacy of their coming-of-age sitcom, which wrapped in 2000 after seven seasons.
In a post on her Tumblr.com page, she writes, "Those years (making Boy Meets World) were among the most warm, hilarious, insightful, educational years of my life and I wouldn't trade them for the world. Another thing I wouldn't trade for anything is the integrity and the heart with which BMW was made.
"Making the decision to do the (new) show involved more conversations than you can possible imagine. These conversations were with (former co-stars) because they were all instrumental in creating and maintaining the heart of BMW. The first comment out of every person's mouth was, 'Let's only do it if we think we can create something as special as we did with BMW.'"
The pair will star as married parents to a pre-teen daughter, and Savage has taken to Twitter.com to share his excitement.
He tweeted, "I'm going to be a father! Well, on TV at least. The Boy Meets World sequel is officially happening!"
