I think she's just mortal like the rest of us and battles with weight gain along with the ups and downs of life. I don't think she's that disciplined like some celebrities are, just down to earth.
So much respect for Sheridan Smith as an actress. I think she burnt herself out with all the parts she had over the last few years.
