Is Jennifer Lopez really dating Calvin Harris? The pair has been seen spending more time with each other which have led witnesses to speculate the two are already dating. Although there are reports that two may be just working on a music together, some say its just a cover up to conceal their blooming relationship.

A source claims that the couple is very careful not to be seen in public together. "It's very early days and they're keeping things on the down-low." Said the source. However, the source also confirms that two have started to become close and the chemistry between the two is undeniable. The source describes it as an "epic chemistry"

Reports about the two started when the 47-year-old "Jenny from the Block" singer was spotted several times with the 32-year-old Scottish DJ at a hotel in Las Vegas with the impression that the two are only together for a music collaboration.

It's a bit hard for fans not to speculate romance between the two after seeing cute posts of the two together during J.Lo's 47th birthday party. Even Harris has posted a video with the actress / singer dancing in a sexy revealing dress. Other stars spotted on J.Lo's birthday are Kim Kardashian and French Montana.

J.Lo brushed aside the speculations as she continues filming a new drama titled "Shades of Blue," where she plays as Detective Harlee Santos who works in the anti-corruption unit of the police department but serves under a corrupt lieutenant.

Calvin Harris has been single for almost four months now after his break up with Taylor Swift. After the split, Swift quickly found love in Tom Hiddleston while Harris has been rumored to be dating Tinashe. Meanwhile, Jennifer Lopez has just broken up with long-time boyfriend Casper Smart a few weeks ago.
