Is Dolly Parton heading to Netflix? According to her "9 to 5" co-star and current Netflix star Lily Tomlin, according to Deadline the answer is yes. During a "Grace and Frankie" panel at the company's headquarters at Raleigh Studios in Hollywood, panel moderator Pete Hammond asked the cast if Parton would be guest starring on the show. The cast was quick to respond that they would love it, but Tomlin suggested that the country superstar might be too busy with her own Netflix show to commit. Netflix has declined to comment on the news.
