Dolly Parton and Sylvester Stallone teamed up for the 1984 film "Rhinestone." In an interview, Parton revealed that she was initially surprised by Stallone's size when they met. She had never seen him in person before and expected him to be gigantic due to his fame from the "Rocky" franchise. Despite her initial surprise, Parton found Stallone to be beautiful and enjoyed working with him on set.

During the filming of "Rhinestone," Stallone's health-conscious and disciplined lifestyle made an impression on Parton. Seeing his commitment to physical fitness and his shock at her junk food eating habits inspired her to reassess her own lifestyle choices.

Parton admitted that she was going through a difficult period at the time and had health problems. Stallone's influence motivated her to make positive changes and prioritize her health.

Parton mentioned in her memoir, "Dolly Parton, Songteller: My Life in Lyrics," that Stallone's health-consciousness and humor were beneficial to her during that time. She realized the importance of changing her ways and adopting healthier habits. Since then, she has practiced moderation in her diet and pays attention to portion control. While she occasionally indulges in breakfasts that include biscuits and sausage, she generally follows a low-carb diet during the week.

Parton also mentioned that being short in stature and having a hearty appetite can lead to weight gain, so she tries to maintain balance and watch her intake.

Overall, Dolly Parton's collaboration with Sylvester Stallone in "Rhinestone" not only resulted in a professional partnership but also had a personal impact on her lifestyle choices. Stallone's dedication to physical fitness and healthy eating habits inspired Parton to prioritize her own well-being and make positive changes.
