Is Calvin Harris secretly dating Jennifer Lopez?

Rumour has it Calvin Harris and Jennifer Lopez have been seeing each other in secret, but is it really true?
According to a source for the National Enquirer, the 32-year-old DJ and the 47-year-old popstar have been seeing each other on the low. "Calvin and Jennifer are very careful to not be seen together. It's very early days, and they're keeping things on the down-low," reported the source.
The insider also revealed that the pair have been spending a lot of time together at a Las Vegas hotel, which they claim is due to a "music project" they are working on together. "They've become really close," revealed the source, "There's epic chemistry between them."
The rumours began back in June when Calvin attended J-Lo's 47th birthday party and it was reported that they were keen on working together. However, it seems a new romance may have sparked between them during their working process.

We'll have to wait and see...
