Viral video chart: Ed Sheeran, Madonna, Andy Murray and 1D's Liam Payne

Clare Balding and Jack Whitehall court danger, a birthday greeting from Game of Thrones, Nicki Minaj joins the queen of pop, and Toy Story

We start this week with a dream come true for an Ed Sheeran fan who was surprised by her hero as she sang hit song Thinking Out Loud. Sydney Bourbeau was performing at her Canadian music school's fundraiser for the Edmonton Humane Society when Sheeran walked out of an HMV store and on to a stage in the shopping mall. Bourbeau, 13, said: "I was like, should I stop? I didn't want to stop, but I wanted to talk to him. This is, like, the best thing that's ever happened to me."

If only tennis fans Clare Balding, Jack Whitehall and One Direction's Liam Payne had been so thrilled to meet their hero. Former Wimbledon champion Andy Murray put them through their paces as he coached them to raise funds for Unicef's Children in Danger Summer Disease Appeal. It was definitely game, set and match to Andy.
