Lauren Silverman has an endearing nickname for her boyfriend and TV supremo Simon Cowell - Dumbo.
Former Britain's Got Talent judge Piers Morgan revealed the name US socialite Lauren gives the father of her son after he dined out with the couple.
"Fun dinner with @SimonCowell and the delightful Lauren," he wrote on Twitter.
"So pleased to discover she calls him Dumbo."
It's not known whether Lauren has named Simon after the elephant in the Disney film.
Simon and Lauren, whose first son together, Eric, was born this year, have been enjoying life since the final of Britain's Got Talent.
Britain's Got Talent judge Amanda Holden recently said she thought Simon will tie the knot with Lauren and have more children.
"He's met his match in Lauren, 100 per cent," she told Hello magazine.
