Priscilla was just 14 when she first met Elvis at a party in 1959 and the couple became inseparable.
She even visited him in Germany while he was serving in the Army and moved to Memphis to be with him in 1963 with the couple marrying four years later.
They welcomed Lisa Marie exactly nine months after their wedding.
Following Priscilla's divorce from Elvis, she went on to star in several blockbuster films, such as The Naked Gun, and had a starring role in Dallas.
