Following the death of Dolly Parton at age 80, Billy sits down for a deeply personal conversation with Dr. John Grossman, the legendary plastic surgeon who worked with Dolly for decades — and, more importantly, became her close friend over a relationship spanning nearly 50 years.

Grossman first met Dolly when she was in her 30s. What began as a doctor-patient relationship developed into a friendship that gave him a rare glimpse of the woman behind one of the most recognizable personalities in entertainment.

And according to Grossman, the Dolly Parton the world fell in love with was exactly who she really was.

He remembers her extraordinary sense of humor, humility, honesty and Southern hospitality. He recalls visiting Dolly at her Beverly Hills home, where she would insist on making him coffee, and describes a woman who never behaved like a celebrity despite becoming one of the biggest stars in the world.

Grossman also shares a remarkable story from 1995. Before discussing their doctor-patient relationship and cosmetic procedures in her book, Dolly made a special appointment with him for one reason: to ask his permission to use his name.

After decades of treating famous patients, Grossman says no other celebrity had ever extended him that courtesy.

The conversation also explores Dolly's fiercely protected privacy, her devotion to her husband of nearly 60 years, Carl Dean, and why Grossman continues to protect the confidential medical information entrusted to him during their decades together.

Billy and Grossman reflect on Dolly's journey from a poor childhood in Tennessee to becoming the best-selling female country artist of all time — and why her death feels like the loss of something much bigger than a music legend.

For Grossman, there simply aren't enough superlatives to describe the woman he knew.
