Simon Cowell: London Birthday Bash

Simon Cowell celebrates the birthday of Sir Philip Green on Tuesday (March 15) held at the Mosimann’s in London, England, UK.

The 51-year-old music executive promised “the best judging panel on The X Factor.” “It’s gonna be a balance between guys and girls, and it should be a balance between people who have been singers and also, like me, have worked behind the scenes and know what they’re talking about it,” Simon told MTV News. “It will be the best judging panel so far. I promise you: If I get the people I want, I’m really happy.”

The judging panel is expected to be announced later this week.
