Simon Cowell is spotted partying at VIP Room in Saint-Tropez, France with a mystery female and is startled when he sees his picture being taken.

Hmm…wonder if his girlfriend knows about this? Well, she does now!

I’m not too sure how “into” this chick that Simon was. He doesn’t look very interested, but she sure as hell does..
