Maybe It Runs In the Family

People is promoting its "Photo Exclusive" of Lisa Marie Presley and her three-month-old twin daughters, Finley and Harper.

Presley, the daughter of American icon Elvis Presley, tells People she wanted to have these babies but had several miscarriages because her blood was too thick. Once she started taking blood thinners, she claims, she conceived — and the result was the twins.

Elvis' fans know that Elvis himself was a twin, but his twin brother was stillborn.

Maybe having twins is a family trait. There's no way to be sure that I know of. Lisa Marie was Elvis' only child.

Elvis died in August 1977.
