The Melissa & Joey star told Digital Spy that her stint on ABC's Dancing with the Stars changed the public's perception of her.
Hart explained: "I was Clarissa for so long, and I thought, 'I'll never get out of that, I'll always be Clarissa'. And then I was Sabrina, and [I thought] 'I'm never going to get away from Sabrina'.
"But then I did Dancing with the Stars... and it made me go from 'Sabrina' to 'Melissa'. All of a sudden, people in airports and out in public called me Melissa, not Sabrina."
However, Hart revealed that many fans still associate her with the role of Clarissa Darling, which she played from 1991 to 1994.
"Now it's come back to Clarissa," she admitted. "It's a little cult hit."
