Robsten fans may have a reason to rejoice. Actor Robert Pattinson has since moved on from his former "Twilight" co-star, actress Kristen Stewart, but according to a report from Radar Online, the British film star may still have feelings for his longtime, on-screen turned off-screen belle.

Despite his relationship of three months with singer FKA Twigs (Tahliah Barnett), insiders claim that Pattinson, 28, is still hung up on Stewart, 24, following their May 2013 split. “Everyone knows he is still broken up over Kristen,” an insider told the site. According to the source, Twigs may feel she comes in second to  Stewart, his ex-girlfriend of three years. “I am sure that this girl is worried that she is a rebound,” an insider added.

Contradictory to allegations Pattinson is still allegedly pining for Stewart, the report also states that he has been steady in his romance with Twigs, 26. Insiders say that couple, who are reportedly not engaged despite previous claims, are getting "very serious." "They're living together full-time..." a source said.

The latest claims about Stewart and Pattinson’s relationship comes on the heels of a report from the Daily Mail last month which suggested that the actor was considering relocating back to London with Twigs in order to get away from the “Twilight” actress. “…He seems keen to make a fresh start away from the mutual circles he shared with his ex-girlfriend Kristen in L.A.,” a source said.

Pattinson last spoke out about his split from Stewart during an interview with Esquire UK in July. Over one year after their split, which reportedly occurred following her affair with her then married “Snow White and the Huntsman” director Rupert Sanders, Pattinson told the magazine he was over their break up. “S--t happens, you know?” he said. “It’s just young people… It’s normal! And honestly, who gives a s—t?”

Pattinson and Stewart were last seen at the Hollywood Film Awards in Los Angeles Friday night. According to a report from Hollywood Life, despite the duo both presenting various awards during the show, the duo did not interact throughout the televised affair.
