Jennifer Lopez has dismissed rumors she has started a new romance with Dancing With The Stars star Maksim Chmerkovskiy.

The On the Floor hitmaker reportedly split from her dancer beau Casper Smart earlier this month (Jun14), and speculation spread this week (begs09Jun14) that Lopez has been quick to move on with another dance professional, Russian ballroom expert Chmerkovskiy.

However Lopez addressed the rumors on Thursday (12Jun14) after reading a tweet from Pittsburgh, Pennsylvania radio station Qburgh which suggested the singer was dating again. While preparing for her World Cup launch performance with Pitbull in Brazil, she replied, "No I'm not. #rumors #nottrue".

And when a fan asked her directly if she had moved on from Smart, Lopez replied, "No I'm not. (dating anyone new already)."

Chmerkovskiy previously served as a backup dancer for Lopez during her American Music Awards performance in November (13), and reports suggested she reconnected with him through her best friend, actress Leah Remini, who was a contestant on Dancing with the Stars.

Maksim has been linked to a series of famous females, including supermodel Kate Upton.
