The TV presenter told Metro that it was true that she had described Franco's 2010 collection Palo Alto: Stories as "a brazen Raymond Carver rip-off".
Geldof said: "Everyone said the same thing. I enjoyed it but it was easy to spot who had influenced him and the classes he'd gone to. The people lauding it are his friends."

Asked if she feared that her own upcoming short story collection would receive a similar response, she replied: "Yes, but I feel like I have my own voice now.
"When you find your own voice it becomes a joy to write - you no longer have the ghosts of your literary heroes hanging around. I think I've got to that point but I don't think, dare I say it, James Franco has yet."
The OMG! With Peaches Geldof presenter previously revealed that her short story collection would be about "happiness and melancholy".
She added of the book: "I still haven't finished it. I finished the first draft when I was 16 but then I read Raymond Carver for the first time and I burnt it - I thought, 'This is s**t'. I wanted to simplify my work like he did.
"Then I read John Cheever and Bret Easton Ellis and started again. I finished when I was 19 but my computer got stolen and I hadn't backed any of my work up. I was really upset. I'm now halfway through the current version."
Quizzed on the subject matter of the book, Geldof said: "The woes of being. The mundane and melancholy and how depressing it is just to be."
