AceShowbiz - Pink Floyd rocker David Gilmour and his wife are "deeply ashamed" of their son after he provoked fury by climbing the U.K.'s most important war memorial during a violent student protest in London. The rocker's adopted son Charlie was photographed swinging from the Union flag and clamoring up the Cenotaph, a monument commemorating Britain's war dead, in London's Whitehall during a day of destructive demonstrations over plans to increase university tuition fees.

Charlie has issued an apology for his actions, insisting he feels "mortified" by the "moment of idiocy", and now his father has spoken publicly about the incident, telling Britain's The Sun, "He's thoroughly ashamed of himself."

Gilmore's wife and Charlie's mother, Polly Sampson, adds, "We're deeply ashamed of him and he's deeply ashamed of himself... We are continuing to give him an earful (reprimand him), not that he needs it because he's already so ashamed he can barely speak. I am as ashamed of him as he is of himself."

Charlie, whose biological father is acclaimed playwright Heathcote Williams, was adopted by the famous musician after his marriage to Sampson in 1994.
