We probably all owe T-Pain an apology right about now. Turns out the artist wasn't using auto-tune to cover up a lack of vocal talent.

Surprising the world during a live performance for NPR's Tiny Desk Concert series, R&B and hip-hop artist T-Pain sang three of his popular songs for the first time without auto-tune

Singing live next to a keyboardist, T-Pain ditched his dreads, grills and auto-tune, showing fans and haters that he can actually sing really well. Hitting some high notes, T-Pain sang his hits "Buy U A Drank (Shawty Snappin')," "Up Down (Do This All Day)" and "Drankin' Patna."

"I know everybody is wondering where the Auto-Tune is gonna come from. It's OK, I got it in my pocket ... It's surgically inserted," he joked.

While he kept referring to the experience as being "weird as hell," T-Pain proved he has the pipes to make him a credible artist in the music biz.

The Tiny Desk concert series includes intimate video performances at the live desk at NPR's Music office. Other popular artists that have performed for Tiny Desk include Adele, Edward Sharpe and the Magnetic Zeroes, Macklemore & Ryan Lewis, Yo-Yo Ma, Miguel and Passion Pitt.
