British Princes Harry and William toured the home of The King in Memphis, Tennessee over the weekend (beg02May14) as they checked out Elvis Presley's Graceland mansion as part of a pal's pre-wedding celebrations.

Guy Pelly invited the royals to join him as he said goodbye to his single years with a trip to Elvis' pad on Friday - the day before his wedding at the Hunt and Polo Club Grounds.

Both royals donned Elvis' signature gold glasses for the Graceland jaunt.

After hearing a real future king had toured her former home, Priscilla Presley tweeted, "So happy Prince William, Prince Harry and the wedding group had a good time on their tour of Graceland."

Pelly wed Tennessee native Lizzy Wilson on Saturday after asking her to be his wife in December (13).
