"Gloria Stuart was a force both on and off screen," DiCaprio said in a statement obtained by Us magazine. "An amazingly sweet person, a fantastic actress, and someone who always fought for what she believed in."

"She was one of the last great actresses from the Golden era of Hollywood," he continued. "I was honored to have worked alongside her. She will be missed."

Stuart began her acting career in the 1930's, starring in films including "The Invisible Man," Busby Berkeley's "Gold Diggers of 1935" and two Shirley Temple movies, "Poor Little Rich Girl" and "Rebecca of Sunnybrook Farm."

After retiring in the mid-1940s and a brief acting stint in the 1970s, Stuart reemerged in James Cameron's "Titanic" in 1997, playing the elder version of Kate Winslet's character Rose Calvert.

She earned a Best Supporting Actress Oscar nomination for her role, making her the oldest actress ever nominated for an Academy Award.
