What's Up With the Big Smile, Simon?

It’s kinda creeping us out!
Who knew Simon Cowell could smile so wide?!
Si was snapped leaving Eva Longoria’s restaurant, Beso, with his ex-girlfriend, Terri Seymour, and that wide grin on Thursday night.
They’re sure friendly for a recently split couple!
Did he know he was gonna get some later?
