And it didn’t take long for the pair to talk about their new common ground – babies.
A source said: “Simon and Cheryl bonded over parenting during a private jet and helicopter flight to the house.
“She curtsied for him she first got onto the plane – it was her way of breaking the ice.
“Despite the break they’ve had from each other, they’re still clearly very close.”
