Reports circulated yesterday that Drake and Diddy had an altercation at a club in Miami over the weekend. More details are emerging that make it seem like the fight was over Drake’s one-off “0 To 100/The Catch-Up” that he put out earlier this year. The beat was made by Boi-1da — who also co-produced “6 God” and “How Bout Now” — and an insider told Missinfo that the beat was originally meant for Diddy: “Apparently Diddy was given that beat first, eventually sent it to Drake to put a verse on it, but as we all know Drake released ‘0 To 100′ as a freestyle using the beat instead. Reportedly, the beat was made during a series of sessions in Miami where Puff flew Boi-1da down … but turned down the beat. Which would make it up for grabs.”

TMZ reports that “sources close to Diddy say he confronted Drake, who just blew him off, and that’s when Diddy said, ‘You’ll never disrespect me again,’ and then punched him.” During the fight, Drake hurt his shoulder and “exacerbated an old injury,” which sent him to the emergency room. It makes sense that Diddy would be pissed if what sources are saying is true, considering that “0 To 100″ was just nominated for two Grammys for Best Rap Performance and Best Rap Song.
