Jay Z is the king of cool, and when he joined his wife Beyoncé and adorable daughter Blue Ivy on stage last night at the MTV Video Music Awards, it was officially proven. Dressed to impress in his standard uniform of jeans, black Timberland boots and a white T-shirt, he stepped it up with the addition of a hat. Sleek, manly and totally on trend, he made sure to not upstage Queen Bey (as if that's even possible...), but still maintain his position as hip-hop's most powerful dude. We're taking notes.
