What Oprah And 7 Other Celebrities Learned From Their Grandparents

After premiering in March, Justin Timberlake's recent music video, "Mirrors," gained attention for celebrating a somewhat unlikely subject: his grandparents' marriage.

The video for "Mirrors," which is the second single off his album, "The 20/20 Experience," chronicles his grandparents' 63-year love, with actors depicting their romance from courtship through old age. The beginning of the eight-minute-long clip features a dedication to the couple, which reads: "for William and Sadie."

Timberlake, who married actress Jessica Biel last October, has cited his recently deceased grandfather as a major role model, saying he taught him that "chivalry doesn't have to die with the birth of the Internet." This made us curious about what other celebrities have learned from their grandparents -- and how these lessons have contributed to their personal and professional success.
