London - Simon Cowell's mother thinks he will make a "fantastic father".
The 53-year-old music mogul is reportedly having a baby with his friend Andrew Silverman's estranged wife, New York socialite Lauren Silverman - and his 87-year-old mum Julie can't wait to become a grandmother.
She said told The Sun newspaper: "I've not heard anything officially. But if it's true then I'm absolutely delighted. It's wonderful! He'll make a fantastic father. He'll be great."
Rosy Davis, who is married to Lauren's father Steven, confirmed the news and admitted her family are "excited" that she is welcoming a child with the X Factor boss.
'Boycotted their wedding'
She told MailOnline: "We are all excited for the baby. It's beautiful. We feel blessed. Any kid is a blessing."
Andrew reportedly filed for divorce from 36-year-old wife Lauren - who is said to be 10 weeks pregnant - on July 15 and is believed to have filed his affidavit on July 24.
The estranged couple also have a seven-year-old son called Adam.
It has also emerged Andrew's parents Eleonora and Allen never attended his and Lauren's wedding because they reportedly had concerns about the brunette beauty.
A source told the website: "Andrew's parents boycotted their wedding because they had their doubts about Lauren. They thought she was suspect."
Simon and Lauren are believed to have met on holiday in Barbados some years ago after being introduced to each other by Andrew, and the trio have shared many vacations since.
The source added: "They would organise these month-long trips and Andrew would go for two weeks and then leave for business and Lauren would stay behind.
"And people talked when she left their little boy at home and stayed away for a month."
