Betty White just took a nothing day and made it seem worthwhile in a tribute to her friend and former co-star Mary Tyler Moore .

Dozens of celebrities have posted messages about the legendary actress following her death on Wednesday at the age of 80, but most didnt have the relationship and history Moore shared with White.

One of Whites most memorable roles was appearing as Sue Ann Nivens alongside Moore in the groundbreaking 70s sitcom The Mary Tyler Moore Show.

White remembered her friend on Thursday in a touching Instagram post featuring the pair posing with their former and late husbands, Grant Tinker and Allen Ludden. Tinker, Moores husband from 1962 to 1981, died in 2016, while Ludden , Whites husband of 18 years, died in 1981 of stomach cancer. (Moore married Robert Levine in 1983; White never remarried.)

Mary Tyler Moore, Grant Tinker, Allen Ludden and I had some of the best times of my life together, wrote White. She was special.
