"Jemima is now just friends with the Notting Hill star and has been quietly seeing entrepreneur Ben Elliot," the Daily Mail reported today, quoting sources close to the former wife of ex-Pakistani cricketer Imran Khan as saying.

The couple, who have been friends for years and attended Bristol University together, were photographed recently leaving a nightclub here.

According to a fellow reveller, the pair, who arrived and left together, were "virtually cheek to cheek". "Jemima was all over Ben, they looked very natural together. They were incredibly close.

"They were only there for about half an hour but their body language spoke volumes. It looked more intense than just a friendly chat. Jemima was wearing a revealing short dress with a cut-out flower shape on the front showing her cleavage.

"She had her hand on Ben's knee at one point and was constantly whispering in his ear. They were getting on famously. They were inseparable the whole time they were there and they left together. They got into a cab and drove off," he was quoted by the daily as saying.

Ben, 31, and single, and Jemima, who has two sons from her marriage to Imran Khan, have also been spotted out together at another West London nightclub recently, where they attended an evening hosted by the Referendum Party, the daily claimed.
