Kristen sends Rob ‘ultimatum’

Kristen Stewart

Kristen Stewart reportedly sent Robert Pattinson an ‘ultimatum’ about his dating activities, after she got upset that he moved on so quickly.

Rob and Kristen ended their relationship in May after dating for four years, following her infidelity with director Rupert Sanders last year. The pair were caught kissing in secluded stop-offs around Los Angeles in July 2012.

23-year-old Kristen is said to be deeply hurt at him being linked with girls so soon after they broke up.

“She wasn’t happy — to say the least — that Rob’s been dating other girls [Elvis Presley's granddaughter Riley Keough, for one, and now Dylan Penn] so soon after they split,” a source told the US edition of OK magazine.

“She told him he was cheapening everything they’d had between them.”

Rob has been linked to Riley and Sean Penn’s daughter Dylan, but according to reports they were not serious relationships.

While 27-year-old Rob allegedly did have a fling with Riley, the relationship didn’t last long.

“It was never anything serious, but things did happen between the two,” a source told Hollywood Life.

Meanwhile Riley’s mother Lisa Marie slammed the reports, telling host Andy Cohen on Watch What Happens Live that the rumours are “silly”.

She also insisted that Riley and Kristen are “best friends” and the reports of Riley dating Kristen’s ex-boyfriend are patently untrue.

“I don’t want to say who she’s with or not; I will say who she’s not with and that is a complete lie, and the silliest thing I’ve ever heard, is that she was with Robert Pattinson because her and Kristen Stewart are like best friends,” Lisa Marie said. “So that was the craziest rumor that I will put to bed.”
