The Melissa & Joey actress was paired with Mark Ballas for Dancing with the Stars's ninth season, but the duo were eliminated in week six.
Hart admitted that she doesn't have many happy memories of the ABC reality competition while speaking Access Hollywood on Wednesday (July 25).
"I didn't have the best time on that show… I enjoyed it, but I don't know if I would go back," the star said.
She further explained: "[Dancing with the Stars] was the first time I ever left my children. I left them on the East Coast, came to the West Coast to do it… It doesn't always pan out the way you want it to."
Kate Gosselin is among the celebrities rumoured to be returning for the ABC series's first-ever 'All-Star' season.
The Dancing with the Stars: All-Stars cast will be announced on Friday (July 27).
