What A Hound Dog! Is Robert Pattinson Dating Elvis' Granddaughter?

The actor who played Edward Cullen and the target of many a frenzied tweenage fan melt-down, Robert Pattinson, is set to be back in the game; only weeks after his split with Twilight co-star and long-term on/off girlfriend, Kristen Stewart. The Daily Mail reports that the pair were spotted speeding around L.A in Rob's pickup truck over the past weekend.

The relationship, described as "short-term lust right now rather than long-term love" by The Mail's source, is rather too out in the open for heart-broken Stewart, who is said to be "devastated" that her long-time lover has moved on from her since their May split. After the initial reports that Rob was dating 'I Kissed A Girl' singer Katy Perry, this last rumour is just a bit too painful for the 23- year-old. Keough and Stewart are said to be good friends after meeting on the set of 2010's The Runaways movie where they co-starred. Keough was certainly close enough the On The Road actress to be invited to her 23rd birthday celebrations - she was pictured attending Stewart's Mexican cantina birthday party.

No wonder Kristen's feeling betrayed - she claims to have mentored Keough and encouraged the model to pursue acting more. Still, it's early days for Rob and Riley even though they're apparently in the "inseparable" phase, and it could even be a bit of fan-boying on Pattinson's part: "Rob's awestruck that he's dating someone related to Elvis as he's a massive fan of rock 'n' roll."

Luckily, Stewart's not around to run the risk of bumping into the doe-eyed couple, she's staying at the 'Heartbreak Hotel' (not really) in Paris to attend a Chanel Haute Couture show where she managed to hide her anguish long enough to dazzle paps on the red carpet. Not saying she was smiling but, well, she looked normal.
