Ellen DeGeneres: 'very sad' to see Simon leave 'Idol'

Ellen DeGeneres begins filming "American Idol" today -- the same day Simon Cowell announced he's leaving the show!

"He announced he's leaving on my first day. I'm trying not to take it personally. But seriously, I am going to be very, very sad to see him go, because I think he's made the show what it is," DeGeneres tells her audience.

The talk show host added, "He's a huge part of that show but he wanted a change," adding, "I wish him all the luck in the world hosting 'The Tonight Show.'"
