UPDATE: Riley Keough's rep tells Just Jared that Keough is not dating Robert Pattinson, and that the two were not photographed together last weekend.

ORIGINAL STORY: Robert Pattinson is reportedly dipping his toes into music royalty's pool, as the "Twilight" star is rumored to be dating Elvis Presley's granddaughter, Riley Keough.

Pattinson and Keough, Lisa Marie Presley's daughter, have been spending quality time together and were spotted driving around L.A. over the weekend, according to People.

Ironically, Pattinson's could-be new flame is friends with his old flame Kristen Stewart. Keough co-starred with K-Stew in 2010's "The Runaways," and The King's granddaughter reportedly attended Stewart's 23rd birthday party in April, as did Pattinson.

Stewart and Pattinson ended their on-again, off-again three-year relationship this past spring, despite staying together for nearly a year after Stewart's affair with her married "Snow White and the Huntsman" director, Rupert Sanders.

As for Keough, the 24-year-old previously dated actor Alex Pettyfer ("Magic Mike"), to whom she was supposedly engaged, and was romantically linked to spikey-haired singer Ryan Cabrera.

Only time will tell if these two are in fact making sweet, sweet music together.
