Simon Cowell’s former good friend was reportedly “shocked” to learn the extent of his alleged affair.
Andrew Silverman was alerted to a picture of The X Factor boss and his wife Lauren Silverman kissing on a boat trip in August 2012.
This week it emerged she was pregnant with the music mogul’s child.
Sources told TMZ that Andrew had no idea they had continued a romantic relationship for that long behind his back.
To make matters worse, the betrayed was on the same yacht at the time of what looked like a steamy clinch.
The website was told Andrew feels mortified that his spouse and close pal had been secretly seeing each other.
Simon is refusing to comment on the situation because there are too many “feelings involved”.
He spoke out while promoting the next season of The X Factor USA at the Television Critics Association in Beverly Hills on Thursday.
"There are a lot of things I will eventually clear up when the time is right, but I really have to be sensitive because there's a lot of people's feelings involved here,” he told People magazine.
Earlier in the day he avoided questions, about the 36-year-old woman who is ten weeks along, at the event by cracking jokes.
Simon, 53, was joined on a panel by fellow talent show judges Demi Lovato, Kelly Rowland and Paulina Rubio.
"I haven't read the newspapers," he told press. "Unfortunately at this moment I have to keep it private."
Andrew reportedly filed divorce papers in New York listing "adultery" as the reason for parting ways.
He is determined to keep mum on the situation to protect his "top priority”, his seven-year-old son Adam "while working to resolve all outstanding issues with my wife."© Cover Media
