He probably replaced T-Pain because T-Pain is so effing busy now... he has some dominating songs at radio now, with a few more coming. Think about it. He's featured on, not only this, but on Good Life, Shawty, Cyclone, and Kiss Kiss.
^He's also on DJ Khlaed's "I'm So Hood" and of course on his own songs.
But if I were Fabolous I would have waited for an opening in T-Pain's schedule to shoot the video.
Minus T-Pain in the video could take away from the songs overall success and this song has so much hit potential.
If so, this video just got a whole lot hotter.
