ROCK YOUR BODY singer Timberlake had previously spoken about the influence Presley has had on his work, as well as their shared birthplace in Memphis, Tennessee.
But the young star's grandmother SADIE BOMAR reveals that Timberlake's grandfather BILL was a guitarist who jammed with Presley when he lived just a few blocks from the late star.
She says, "Elvis would play for all the men down at the fire station (where Bill worked). Justin started out playing Elvis songs with his grandfather. He just loves Elvis."
