Simon Cowell has become smitten after he began dating the ex fiancée of Formula 1 driver Jenson Button, Louise Griffiths.

Serial dater Simon Cowell, 53, is said to have been on several dates with Louise Griffiths, and is now very taken by her.

Louise Griffiths, 34, began dating British motorsport driver Jensen Button in 2000 before getting engaged to the track star three years later.

But in 2005 they called off their wedding three months before they were due to tie-the-knot.

A friend of singer songwriter Louise Griffiths, who was once a contestant on BBC’s Fame Academy, said that despite Simon Cowell’s obvious commitment issues, the pair are really falling for each other.

The friend told The Sun: “She and Simon have started to get very close. It is early days but there is certainly a chemistry between them.”
