From the outside, Ashton and Demi look like the happiest freakin' couple on the planet. But do they have us all punk'd? Are they really on their way to divorcing over Ashton's alleged infidelity? Probably not. Apparently the two of them have an open marriage, and so while this whole thing might have been embarrassing, it wasn't wholly prohibited. Besides, if Demi married someone her own age, would he send her love tweets?
