During a panel appearance at the 2020 Television Critics Association, the actresses opened up about what it was like growing up in front of the camera – and how they leaned on each other to block out the unwanted and unnecessary negativity from viewers.

"It's really difficult to grow up in front of millions of people who have an opinion on everything you do, and who are allowed to say it at any point," said Winter. "[They] think they know you really well, and they think they can comment on everything you wear, everything you do, or how you grow up and change."

"We have great support in each other. It's made us stronger as we get older," the Smurfs: The Lost Village voice actress continued.

"I think Ariel is such an amazing woman and has always been so mature and handles it with such grace and poise," Hyland added. "I think, between the two of us, we really have gone and tackled them with all of our spite and wit."
