Speaking on the red carpet at the Prince’s Trust And Samsung Celebrates Success, Simon shared the wise words he offered David.
“I said to him, ‘you’re not the only person in this situation.’ That’s a cliche thing to say but it’s true,” Si explained. “Don’t feel too sorry for yourself.
“It’s bad news and I feel bad for him but he has to carry on with his life.”
The music mogul then appeared to suggest that David and his wife Lara Stone could reconcile, adding: “She’s a nice girl… they’ll work it out.”
David is yet to speak out following the marriage split reports, and it’s believed that he and Lara have agreed to a “trial separation”.
Earlier this month, a source stated: “Everyone thought the marriage was strong.
“David is used to hiding his emotions with comedy because that’s what he’s always done. But on the inside it is a real wrench.
“[He] hopes it is a blip and that they can get the marriage back on track somehow, especially seeing as there is a child involved. He is still fiercely protective of Lara.”
The series will return to ITV later this year.
