Without wishing to play down the seriousness of what's being alleged by the teenagers mother, I have to wonder why, or even how, a person seemingly with a high profile media prensence, would/could make contact with some random teenager and pay them serious amounts of cash to send photos or even perform such acts.
Likewise why/how would this child contact the tv presenter and offer their services, if indeed it was they who insitigated the interaction.
I'm not sure that I buy the claims of the mother that this so called interaction has driven the child to drugs.
