He may be flirting up a storm in the Celebrity Big Brother house, but it looks like Calum Best is not as single as he is letting on!

According to reports, the reality star has a lady waiting for him on the outside – and it’s none other than actress Liz Hurley!

Are you as surprised as we are?!

Sources have revealed that 33-year-old Calum and the 49-year-old Bedazzled star enjoyed a secret date together just weeks before the renowned playboy entered the house.

An eyewitness told The Sun newspaper that the unlikely pair shared dinner at Blakes Hotel in South Kensington, with the date seeming to go down very well.

“They were being very flirty and laughing at each other. Liz was dressed up in a very pretty outfit and seemed to find Calum very charming. When they were leaving, they realised a photographer was outside and so left a bit apart,” the source said.

We guess we’ll just have to watch this space. Liz may want to give CBB a skip, however, judging by just how well Calum is getting on with model Cami Li!
