Anne Robinson makes 'Blue Peter' star cry

Anne Robinson made Blue Peter legend John Noakes cry during filming for The Weakest Link.

The acid-tongued host taunted Noakes about his beloved dog Shep at a recording of a special Blue Peter edition of the quiz show on Thursday night.

John presented the children's magazine show in the 1960s and 70s. He grew so attached to the programme's pet Border collie that he was later allowed to keep the pooch as his own.

Speaking to Noakes in between rounds on the programme, Anne demanded: "Where's Shep? What happened to Shep? Did he die or just run away?"

As he broke down, John admitted: "You've made me cry, not many people make me cry."

A source told The Sun: "Anne annoyed John and he got very emotional. The audience didn't seem too happy with Anne either and some even booed. I think Anne knew she had gone too far. As soon as John started crying she stopped the questioning."
