Ronan Keating has said he regrets writing his memoir a decade ago - because it was not interesting enough.
The former Boyzone star said he would advise his younger self to have waited until later in life rather than writing the 2001 autobiography when he was 24.
In an interview for the Smooth Radio Book Club to be broadcast on Saturday, he tells presenter Lynn Parsons: "Really that book was a little premature. I was a kid when I wrote that."
His admission comes as more and more young stars are persuaded to publish their stories after barely any time in the public spotlight. Jessie J, who is also 24, has a book deal despite releasing her debut album only 18 months ago, and X Factor judge Tulisa Contostavlos, also 24, will release her memoir next month.
In contrast, Rolling Stones star Keith Richards was 66 when his acclaimed book was published, and Rod Stewart - whose autobiography comes out this year - is now 67.
Since Ronan's book came out he announced his group has reformed, he separated from wife Yvonne after 14 years of marriage, and his friend and bandmate Stephen Gately died three years ago.
"I came out of a successful boy band and my solo career was doing well; all these offers on the table to do a book," he says in the interview.
Speculating on advice for his younger self about writing a book, he said: "I would have said don't - wait. I could write a hell of a book right now.
"I mean what's happened since, losing Stephen, you know everything that's happened in my life, you know separating from my wife, you know everything that happened, yeah that book just got far more interesting that's for sure."
