To witness the bond between "Office" co-stars Mindy Kaling and B.J. Novak, just follow them both on Twitter -- it's all inside jokes and silliness. Though the "Mindy Project" star recently brought B.J. to the Met Gala, they just went as friends. The pair constantly have to confirm that they aren't dating, but B.J. has said, "We are pretty inseparable best friends with a lot of chemistry."
