Speaking of the tune - which is the first cut to be taken from her upcoming tenth studio LP - Lopez told Duran: "To be here, making your tenth album and listening to our single is a dream come true.
"I just feel so grateful, I don't even know how everything happened."
When asked about her new LP - which is rumoured to be released in November this year - Jennifer said: "I think we're going to release this first and then a few singles and then we'll decide when to put the album out.
"The way the industry is going... I'm more a believer of letting it gain momentum. Let there be demand for the album by putting out some great music first."
In the same interview, J.Lo also confirmed plans to release a 3D concert movie, which she claimed would touch on her split from hubby Marc Anthony.
She said: "I'd been through a big change in my life with the divorce and everything, and as crazy as we are we thought let's put that on camera!"
