Dolly Parton dressed as a Playboy bunny for her husband Carl Dean's last birthday! When Access Hollywood's Kit Hoover asked the singer about his reaction, she joked that he "did about have a heart attack." She also shared what makes her marriage work, her philosophy on beauty and her memories of meeting a young Keanu Reeves. Dolly, who is a Duncan Hines paid spokesperson, also dished on their delicious collaboration. Dolly Parton x Duncan Hines cake mixes and frostings are available Jan. 26.
