'Telephone' by Britney Spears featuring Lady Gaga

Lady Gaga may be the one known for one of the hottest songs ever released, her collabo with Beyoncé, but in reality the song was actually written by Gaga and Darkchild for Britney's infamous Blackout album. Back in 2010 Britney's heavily-autotuned version leaked. It was a sonic masterpiece, but today we were just treated to something special.

A new version of the track has leaked which features both Gaga's and Britney's vocals sans autotune! Without the heavy manipulation of her vocals, the song sounds refreshing and Brit's vocal clarity is beautiful. With different instrumentation and production, the song is wildly different but equally amazing.

It may just be a demo, but we finally have the Gaga/Britney duet we've waited years to hear. Can you imagine if these two had originally hooked up for the final product? Beyoncé who?
