Cowell left speechless by Kenyan poverty

Simon Cowell was left speechless during a visit to Kenya earlier this year.

The music mogul filmed charity special Idol Gives Back with American Idol host Ryan Seacrest in Nairobi this January - and he was shocked by the desperate situation in the region.

"The first day, we rode to a slum and it was worse than anything I had imagined - the ground is moist with sewage, people are so sick," Seacrest told WENN.

"At one point, Simon just had this look on his face like he was going to be sick, and he said, 'I've just got to sit down somewhere. I just can't see anymore right now.'"
