The X-Factor judges now live just a stone's throw away from each other in west London after Cole bought a £2 million luxury apartment following her divorce from footballer Ashley Cole.
A friend of the singer told the Daily Mail: “She is over the moon to have a place that will be her safe haven in the UK. She felt lost in the Surrey mansion near Godalming, her former marital home, where she was too far away from her friends, her work – and from Simon. This is the first time since her divorce that she’s felt as if she has a place she can call her own.”
And Cole, 27, is also rumoured to be looking for a crash pad near mentor Simon, 51, in the US.
The insider continued: “They are very close, so she is thrilled to be living near him and will be looking for a place to rent in LA that’s not far from Simon, too.”
