Bedazzled auto-tune advocate T-Pain has been called out by his former group, Nappy Headz, in the new documentary 'The Untold Story: Nappy Headz.' The documentary tells the story of the Tallahassee, Florida group, who gained notoriety in the South, years before Pain launched his solo rapping career.

According to the doc, the group originally disbanded with the intention to gain exposure as solo artists, then loop in the rest of the group once one of them had secured a record deal. However, after signing with Akon's Konvict Muzik, Pain went on to release three solo albums, with a fourth titled 'Revolver' on the horizon, without a mention of the Nappy Headz to be found.

"I'm just disappointed in the way he let the success get to him," a member of the group says in the film. The doc features Florida legends like TJ Chapman of TJ's DJ's, and Shaheed Najm, Pain's estranged father and former Nappy Headz manager. Najm previously criticized his son for allegedly turning his back on his groupmates and family for Akon, whom he called a "bad muslim," and "con artist."

Pain has yet to comment on the film, or his father's allegations. To check out a trailer for 'The Untold Story: Nappy Headz,' or purchase the DVD, click here.
