The meeting is likely to mark the first time the lovers have been spotted together since the world learned of their affair, which took place while Lauren was married to real estate developer Andrew Silverman.
A source told MailOnline Lauren is “excited” to see Cowell — who was in England promoting his brainchild boy band, One Direction — as it will mark “the first time she has actually laid eyes on Simon in weeks.
“She really loves him and they can’t wait to be together.”
In France, the 36-year-old socialite displayed her baby bump through her 12th week of pregnancy, wearing a black top and white jeans. She brandished a diamond eternity bracelet Simon gifted her with a value of $16,000.
The 53-year-old X Factor boss reportedly helped Lauren finesse a settlement with her cuckolded husband Andrew by smoothing things over in a meeting in the Hamptons earlier this month, as he’d been named in Andrew’s initial divorce papers.
According to the NY Post Thursday, Simon “wanted a face-to-face meeting to clear the air and make sure Andrew wouldn’t speak out about him” and take his name out of the divorce papers.
“No money changed hands, but Simon made Andrew feel good, said he feels bad about the situation, he will take care of everything and he hoped they will remain friends,” the source told the paper. “Andrew really wants to keep his friendship with Cowell.
“The meeting ended with them shaking hands and an agreement their discussion would remain confidential.”
Andrew has a 7-year-old son with Lauren, who is also named Andrew.
