"I honestly can't believe it's been 20 years. I feel old!" Hart revealed in an interview with Nutrisystem before spilling on a few Sabrina secrets.
"Nearly six months before the TV series premiered, Sabrina's 'unofficial pilot' premiered as a TV movie on Showtime," she dished. "In the movie, Sabrina's last name was Sawyer. Ryan Reynolds portrayed Seth, Sabrina's short-lived love interest."
Another secret? After Salem, Hart just "can't do cats anymore." "It was always fun [having cats around], but it was always a challenge," she shared. "The set smelled like cat food -- it was kind of gross."
While Hart has made up her mind about Salem, whether or not the show will return as a reboot is another story.
"There's a lot of talk about a Sabrina reboot. I feel like almost every day, somebody's calling me about it. 'Would we do it? Should we do it? How do we do it?'" she said. "I think the things about reboots is they're really hard to do. They're hard to do right. I think sometimes it's better to just leave it in the past unless you do it really, really great."
Getting the cast back together doesn't seem to be a problem, as Hart said she's still very close with Beth Broderick and Caroline Rhea, who played her aunts Zelda and Hilda.
"I have love for both of them," she gushed, refusing to name Sabrina's favorite. "We, all three ladies, have strong personalities, and there are times we'd all get along, and times when we all were fighting, but we have a close relationship now."
ET was on the set in 2014 when Broderick reunited with Hart for a special Halloween episode of Melissa and Joey.
