"After 50 years of marriage, Papaw Phil finally gave Mamaw Kay a wedding ring for Christmas," tweeted Sadie Robertson, the couple's granddaughter, along with a photo of Kay showing off her sparkler.
Robertson, 67, and his wife, known to viewers as Miss Kay, first married in 1966.
While the Robertsons were celebrating their union, A&E aired a Christmas Day Duck Dynasty marathon, despite Phil's indefinite suspension from filming.
