U2 star Adam Clayton has become a first-time dad, according to reports.
 
The rocker, 50, and his unnamed French girlfriend secretly welcomed the tot into the world almost a year ago, according to the Irish Independent newspaper.
 
Clayton is the last member of the rock supergroup to become a father.
 
Details of the birth and the identity of the mother are being kept a closely guarded secret - but insiders tell the publication the baby was a boy.
 
An source tells the Independent that the bassist is "deliriously happy with fatherhood."
 
Clayton was previously engaged to supermodel Naomi Campbell and longtime Canadian girlfriend Susie Smith - but both romances fizzled out.
