Now, it appears, he has been let down again. 'For all his waywardness and addiction I adore Christopher and just want him healthy and well,' the actor added.
Those close to Brosnan suggest his second wife, Keeley Shaye Smith, may be behind the decision to cut off Christopher.
Brosnan, who played 007 in four films before his recent replacement by Daniel Craig, has two children by Miss Shaye Smith - Dylan Thomas, eight, and Paris Beckett, four.
Charlotte, Christopher and Sean, 21, the son Brosnan had with Miss Harris, have all made it clear they do not like her.
A friend of Christopher, who saw him recently, said last night: 'He was pretty high and probably doing other things, although I didn't see what.
'He didn't mention that his dad had cut him off. The subject of his dad is never raised unless he brings it up.'
