The 21-year-old's new show, OMG! With Peaches Geldof, begins on ITV2 on March 2 and she will try and help to solve people's problems by drawing on her own experiences.
However, according to UK newspaper The Sun, she said: 'I'm not well-placed to help people with their problems because I'm not medically trained.
'I may have had a lot of life experience, but therapy is a job you need to be trained in.'
The star, who has already been through a marriage and divorce herself, said her friends never ask her for advice.
She said: 'I wouldn't say that I'm particularly the agony aunt.'
