While the majority of us have spent much of this week sitting in darkness, our windows draped in old towels in a fruitless attempt to stave away the blistering 40 degree heat, Victoria and David Beckham have been sailing the mediterranean with their two youngest children Cruz, 17, and Harper, 11.

Not unexpected, the Beckhams are known for their love of lavish holidays, yachts and rich friends with ample holiday homes. What is unexpected, however, is their friendship with Sarah Ferguson, who they bumped into at Lo Scoglio da Tommaso restaurant in Amalfi on Monday.

Russell Brand and Helen Mirren

The Oscar-winning actress and comedian met on the set of the 2009 film The Tempest, where they formed a fast friendship.

Several years later Mirren gave an interview to BBC America, where she spoke of her unlikely chum, saying: “The thing about him is he likes women, and not a lot of men do. That’s why women like him. He’s genuinely interested in us. Women melt in his presence,” she said.
