DJ Envy asked B.o.B about his successful collaboration with T-Pain on "Up Down." The song found it's way into radio rotation and on the lips of fans many and T-Pain's seemingly quick comeback surprised many.
To answer DJ Envy's question, B.o.B said that he's not the type of artist to chase after someone who's the most popular artist to work with. Music is not about making a 'power move' for B.o.B and he doesn't want his music to be a "star-studded event." If he believes in the artist and the music then he's happy to join the fun.
At the end of the day, B.o.B is still a fan of T-Pain.
