Singer Ronan Keating says he regrets writing his memoir a decade ago – because it was not interesting enough.

The former Boyzone star says he would advise his younger self to have waited until later in life – rather than writing the 2001 autobiography when he was 24.

Since the book came out – he announced his group had reformed, he separated from wife Yvonne after 14 years of marriage, and his friend and bandmate Stephen Gately died three years ago.
