The mystery woman who was photographed with Robert Pattinson over the weekend is not Elvis Presley’s granddaughter, Riley Keough, a representative of the actress told  

Photographs of Pattinson and the woman, who is said to closely resemble Keough, showed the couple driving around Loz Feliz in Hollywood after picking up a ping pong table. They are believed to have headed straight to Pattinson’s home soon after.    

“Riley isn’t dating Rob. And I can confirm that Riley was not photographed at all this weekend,” a representative of the ‘Magic Mike’ actress said, attempting to debunk rumors that Pattinson’s mystery woman is Keough.

A friend of the British actor, too, confirmed that Pattinson is not dating anyone after splitting from longtime girlfriend Kristen Stewart, who is said to be a friend of Keough’s.

"Rob is just enjoying hanging and chilling with friends at this point in his life," the friend told E! News. “[He] isn't dating anyone at the moment, but he is very open to it.”

The latest news comes just a day after the Daily Mail quoted a source close to Pattinson as saying that he and Keough, who met through Stewart, while she was filming ‘The Runaways,’ are always together.

“They're inseparable. Rob loves the fact that Riley is Elvis's granddaughter - that's true Rock'n'Roll royalty in his eyes,” a source told the Daily Mail, adding that the couple will be spending 4th of July together before Pattinson starts filming ‘Map To The Stars’ in Toronto on Monday.

The Daily Mail source described the relationship as “short-term lust right now rather than long-term love,” but said they bond over their mutual love for music.

Stewart, in the meantime, is said to be devastated about Pattinson’s alleged affair with Keough. Stewart, who co-starred with Pattinson in the ‘Twilight’ series, has made it known to her former boyfriend that she is not happy with him dating Keough.

“Kristen is emotionally volatile at best of times and flew off the handle when she found out about Rob's liaison with Riley. She's told Rob via friends she feels violated,” the Daily Mail reported.
