So is Robert Pattinson really Riley Keough's lovin' teddy bear or not?

Rumors have swirled this week that the Twilight star is dating the 24-year-old actress and granddaughter of Elvis Presley.

However, Riley's rep has now weighed in on the situation and is shooting down rumors of a romance between the two, according to Just Jared.

"Riley isn't dating Rob," her rep says. "And I can confirm that Riley was not photographed at all this weekend." 

Rob had been photographed with a mystery girl in his pick-up truck over the weekend, and the media had identified Riley as the lucky gal.

However, we all know that celebrities love to deny relationship rumors for as long as they can, so it's still possible that Rob and Riley are in the process of getting to know each other.

After all, there have been so many sources discussing Rob and Riley  including rumors that Kristen Stewart is "livid" about her The Runaways co-star dating Rob  that it's hard to believe the whole thing is completely made-up.

But even if Rob and Riley aren't dating, somehow we doubt Rob is lonesome tonight.
