See Anderson Cooper and Gloria Vanderbilt’s Best Mother-Son Moments Before Watching Their Documentary

Gloria Vanderbilt has lived quite a life in her 92 years. The heiress was at the center of a highly publicized custody battle in the 1930s, which, at the time, was dubbed the "trial of the century." She went on to become an actress, artist, and blue jeans designer while embarking on one whirlwind romance after another (her famous past loves include Frank Sinatra, Marlon Brando, and Roald Dahl). And in the midst of it all, Vanderbilt became a mother. She had two children with her second husband, Leopold Stokowski, before her fourth marriage to Wyatt Cooper produced two more sons: Carter and Anderson Cooper.

In the new HBO documentary Nothing Left Unsaid: Gloria Vanderbilt and Anderson Cooper, the 48-year-old journalist sits down with his mother for a tell-all interview. It’s a no-holds-barred discussion in which the pair discuss the drama of Vanderbilt’s childhood, her rocky relationships, her passion for the arts, and the tragedy of her son Carter’s suicide in 1988.

The conversation gets unsurprisingly heavy, hitting its most arguably emotional point with a visit to Carter’s gravesite. But through it all, the interview continues—and the banter between Cooper and his mother often outshines the sadness while Cooper discovers previously unrevealed facts about his family. Ultimately, this deep-dive inside the mind of one of America’s most glamorous living legends is rooted in a mother-son dynamic that’s simply sweet at its fascinating core. Scroll down to see 10 photos of Vanderbilt and her sons throughout the years—and be sure to tune in when the documentary airs April 9 at 9 p.m. ET on HBO. You won’t want to miss it.
