In related news, like a good husband, Nick Cannon took advantage of those hot Black Friday deals by going out and buying his pregnant wife 20 pairs of flats. The actor/rapper/radio personality decided to take matters into his own hands after becoming concerned that his wife might topple over in those high heels of hers.
