*A clip that allegedly features Jennifer Lopez butchering the mess out of the Donna Summer/Barbra Streisand duet “No More Tears (Enough Is Enough)” has hit the Internet. (Scroll down to watch.)

The footage, posted on YouTube over the weekend, is said to be an outtake from J.Lo’s stab at the 1979 hit during recording sessions for her in-limbo album “Love?”

The woman is heard singing several lines way off key, before stopping and yelling: “Wow! I’m sorry everybody, that hurt me, too. Sorry, that sounded so f**king crazy.”

The voice is then heard repeating the lyrics several times trying to hit the right key — laughing all the while at her inability to do so.

Below is JLo’s attempt at “No More Tears,” followed by what the song is supposed to sound like.
