Katie Price has asked her lawyers to write to Channel 4 after comedian Frankie Boyle made a "vile" joke about her disabled son.
Price said she was seeking legal advice after Boyle made comments about her son Harvey, who suffers from septo-optic dysplasia and autism, on his show Tramadol Nights.
In a statement on her website, she said: "Harvey Price is a little miracle. Every day he overcomes so many difficulties with the help of family and medical experts and has so many tiny battles to win due to his medical problems.
"If Mr Boyle had a 10th of his courage and decency he would know that to suggest, let alone think funny, that Harvey may sexually attack me is vile and deeply unfair.
"To bully this unbelievably brave child is despicable, to broadcast it on television is to show a complete and utter lack of judgment."
A message at the beginning of Boyle's programme, which was broadcast on Tuesday night, warned viewers the show contained "very strong language and uncompromising adult content".
A Channel 4 spokeswoman said: "Frankie Boyle is one of the highest profile comedians in the UK, he's well known for his controversial humour and the programme carried appropriate warnings as to the nature of the material.
"The joke aired in the context of a late-night comedy show. The joke itself has been performed by Frankie as part of his stage show and, as with much of his material, is an absurdist and satirical comment on high-profile individuals whose lives have been played out in the media."
In April he had an on-stage argument with the mother of a Down's syndrome child after making fun of the condition.
