The 53-year-old 'Britain's Got Talent' boss, who returned to TV for the new series, said he would love to be a father to a girl child, reported Sun online.
Asked if he would like to have children, Cowell said, "If I knew that I could be, how can I put this delicately, faithful. I do like kids. I haven't ruled it out. I don't think I'd adopt. I'd rather have my own. I would love a girl. But I don't think I'd be good in the first six months."
He also had relationships with singer Sinitta, telly host Terri Seymour and model Jackie St Clair.
