Elvis's granddaughter and Lisa Marie Presley's daughter Riley Keough in sexy cutout dress

LA: Wonder what Elvis would say about his granddaughter now? Lisa Marie Presley's daughter Riley Keough was spotted leaving a Joan Jett concert in Hollywood on Thursday wearing quite the scandalous number. Sporting a black cutout dress, the 24-year-old seemed like she was definitely ready for some rock 'n' roll — or, ahem, a superhot date.

Speaking of dating: Rumors have recently started to swirl that the "Mad Max: Fury Road" star is "hooking up" with Kristen Stewart's ex-boyfriend, Robert Pattinson. But a rep for Riley quickly shot down the reports, telling Just Jared, "Riley isn't dating Rob. And I can confirm that Riley was not photographed at all this weekend."

Well, with that sexy ensemble she's wearing, Rob might want to consider giving her a call!
