Eve -- Backtracks Poorly from Britney Spears Slam

Eve is trying to distance herself from the comments she made about Britney Spears on the new will.i.am song, but her argument just doesn't make any sense.

Eve was a guest on Bravo's "Watch What Happens Live" last week ... where she questioned whether Britney really provided the British-accented voice on "Scream & Shout." Britney's people called Eve's claim "absolute BS."

Today in DC, our photog asked Eve about her comments, to which she replied, "I didn't say anything about her singing. I said something about her British accent. We know it's Britney Spears singing the song. I never said anything."

Here's the thing though ... if you listen to the song -- which unfortunately we did -- 90% of Britney's appearance on the song is the British accent. She only "sings" for a few seconds at best.
