Olivia De Havilland Dishes On Vicious Feud With Joan Fontaine!

At age 99, Oscar winner OLIVIA DE HAVILLAND, one of Hollywood’s last great screen queens, is launching a new career – as an author!

Olivia, the sole surviving star of the 1939 classic “Gone with the Wind,” is putting the finishing touches on her autobiography and wants it to hit shelves next July – just in time for her 100th birthday!

“It’s absolutely astonishing how much Olivia remembers, and how meticulous she’s been in keeping notes all these years,” a longtime friend told The National ENQUIRER.

Olivia’s life story includes regrets about her fiery relationship with her famous sister, actress Joan Fontaine.

A notorious Hollywood feud erupted at the 1942 Academy Awards, where the sisters were both nominated for Best Actress.

When Joan won for her performance in “Suspicion,” she humiliated Olivia by snubbing her congratulations!

The sisters stopped speaking entirely in 1975.

“I married first, won the Oscar before Olivia did, and if I die first, she’ll undoubtedly be livid because I beat her to it,” Joan famously taunted.

Joan actually did die first, in 2013 at age 96.

“Joan’s death affected Olivia greatly; it caused her to reflect and have remorse that they weren’t able to patch things up,” the friend said.

While Olivia suffers from failing vision and hearing loss, the star, who has lived in Paris for nearly 60 years, still “dresses to the nines every day and has her hair done,” said the friend.

“Olivia has every intention of making it to 100 and getting her book out,” the pal said. “She says she may even go on a tour to promote it!”
