Simon Cowell makes David Walliams cry on 'Britain's Got Talent' by making cruel remarks about his recent divorce.

The 44-year-old comedian thoroughly enjoys winding up his co-star on the talent show panel but it seems the music mogul knows exactly how to get his own back and does so by mentioning his bitter split from model Lara Stone last year.

Speaking on last night's (07.04.16) episode of 'Alan Carr Chatty Man', fellow panellist Amanda Holden said: "I might have said this before, but David asked me, 'What shouldn't I say to Simon?' I said don't mention his height, his love life, all these things, and he just went in and did them all. I think this year Simon has out-funnied David, and if David had said something cruel to Simon, Simon comes back with one remark, and it's usually something horrible about David's divorce, and David shuts up with tears in his eyes and carries on judging. I know, but he started it."

But Alesha Dixon believes the harsh comments are all with tongue-in-cheek as David - who has two-year-old son Alfred with Lara - thrives off the "schoolboy" banter with Simon.

She said: "They are like schoolboys. They are really competitive. It is like battle of the ego. They love to hate each other, they are so competitive. It's great entertainment for us."

And, despite the boys' turbulent on-screen relationship, the brunette beauty is convinced the 'BGT' panel has a "nice balance."
