Rita Ora has been romantically linked to a string of high-profile men, and now it looks like she has set her sights on rapper Wiz Khalifa. According to the Sun, the duo continue to fuel rumours of a budding romance after getting close in recent weeks.

The musical duo teamed up in LA on 26 August when they took to the stage to perform their new track Religion. Sources say that their chemistry backstage was "electrifying".

"It was intense and there was a real buzz in the audience when they seemed to get caught up in the moment and held each other at the end of the performance," an eyewitness told the Sun. "But it didn't stop there.

"Backstage, Rita was sitting on his knee and the two looked really comfortable with each other." The insider added: "It was like they couldn't wait to leave and be alone together."

The Body On Me hitmaker first set tongues wagging when she was seen getting close with the hip-hop star backstage at the 2015 Teen Choice Awards. Just two days later they were spotted enjoying dinner together at The Nice Guy restaurant in Hollywood.

Ora, who has joined the X factor judging panel, is back on the market after split from boyfriend Ricky Hil last month. Khalifa, whose real name is Cameron Thomaz, is also single following his split from glamour model-turned-reality star Amber Rose. She field for divorce from Khalifa, citing "irreconcilable differences". The couple have a son together.
