Priyanka and Nick are basically the cutest thing since puppies. Normally PDA grosses me out, but with these two, it's totally acceptable.
That being said, we live in a day and age when women are on the rise, and going against social norms is the new norm.
Women don't have to take their husband's last names, or even get married for that matter. But Priyanka has taken the old fashioned route, and her reasoning is actually kind of sweet.
