Jay-Z flashed that big newlywed smile we've grown to love so much as he stepped out of Butter in NYC last night.

While the story is apparently stemming from weight gain without doing the usual "Def Jam Detox", her rep responded to the story saying, "I don't know if she's pregnant. Let me perform an ultrasound and get back to you." Not quite a denial. So what do you think about the rumors — is Beyonce pregnant?
