That may be true, but there is only one flash going off and the photographer is standing slightly off to to their right.
Notice also that they are obviously on the red carpet where there are flashes going off all around them constantly.
And here's how I know that.
#1- that's a reflection from the flash, but it's not on the opposite side of the sign.
#2 - if you compare this shadow to #3 you'll notice it's lighter, that's because she is closer and getting bounce back from the sign. He's far away so the shadow is darker and more off center.
#4 - same thing, his shadow is more off to his left.
There is only one flash going off and he is just off her right side.
A couple of other things, though she may not look like it, she's wearing more make-up then you think, the only place you see any flash reflection on her is a little bit on her right shoulder - compare that to his face.
And lastly look at her neck, it's darker on her left.
That's the angle of the shot, it looks like it's straight on, but it's not look at the bottom of the sign.
Also notice that I did a crappy job cutting out Mr. Weirdly Short Arms from the background, but was in a rush so just used the drop shadow to somewhat mask the crappy lasso job.
