Have you been singing this one J.Lo lyric wrong?!

The song 'I'm Real' by Jennifer Lopez featuring Ja Rule was definitely one of our favourite jams back in 2001, but some people have just discovered that they may have been signing a crucial lyric VERY wrong.

The lyrical error occurs at the beginning of the song after Ja Rule says, "what's my mother f***en name?"

But what is it that J.Lo responds with?

Is it, "are you Ellie?" NOPE. Does she sing, "are you ready?" NOPE.

Jenny from the block actually responds with, "R-U-L-E"!

She's spelling out Ja's name.

Who knew!
