Music mogul Simon Cowell referred to his yet-to-be-born son as Tad when he saw him via an ultrasound scan.
The 53-year-old felt his baby with partner Lauren Silverman looked like a tadpole, and hence he lovingly called the little one Tad, reports dailymirror.co.uk.
"I called it 'Tad' because it was like a little tadpole - just, like, moving around," said Cowell.
"It really is a miracle. The baby was kind of unexpected. I hadn't planned for that. Once I got used to it, I thought, it's actually not such a big deal," he added.
