Jennifer Lopez - Lopez 'Not Aware' Of Deluna Song Controversy

The Love Don't Cost a Thing hitmaker debuted her single on U.S. radio last month (Jan11), but the tune immediately caught the attention of music fans who pointed out its resemblance to DeLuna's track Party O'Clock, which was released in Europe in November (10).

Both songs were produced by RedOne and feature similar lyrics and harmonies, while Lopez's promo for On The Floor is also said to borrow elements from DeLuna's video.

DeLuna recently accused the superstar of "taking away" her ideas, but insisted she had no plans to sue Lopez, saying, "Business is business."

Now Lopez has broken her silence about the furore and dismissed the criticism after being quizzed about the claims during an appearance on Spanish TV show, Despierta America.

Speaking in Spanish, she replied, "I'm not aware of that... No, I didn't hear about it."
