The recently single singer, who has been friend with Chmerkovskiy, addressed her love life on Twitter.
In response to a radio station tweet that she was already dating someone new, Lopez replied, "No I'm not (dating anyone new already). #rumors #nottrue."
Lopez, 44, recently broke-up with dancer-choreographer Casper Smart after dating him for nearly two years.
The mother of two had repeatedly said that she is "one of those people who does not like to be alone".
