A wedding is different than a baby, i'm sure she is just happy she is pregnant and it's not something you can hide. Alot of people will look silly when there is more pics of her belly.
Exactly. It's not even as if Beyonce and Jay-Z kept their marriage secret altogether, they just kept the wedding hush hush.
It's better to announce a pregnancy at an event like the VMAs than to do an exclusive for one particular magazine IMO.
