DJ Envy & Charlamagne Tha God Offered Singing Lessons From T-Pain...

Did you know that DJ Envy and Charlamagne Tha God are singers?

We didn't either, but they were caught practicing vocals at the radio station while T-Pain was there. The singer even offered to give the two of them some lessons, but they don't look like they'll take his offer anytime soon. There's always the T-Pain microphone and iPhone app.
