The 32-year-old DJ and the 47-year-old singer have grown close in Las Vegas while working on new music together and their relationship is believed to still be quite new.
A source told the National Enquirer: “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. They’ve become really close. There’s epic chemistry between them.” WOW!
Calvin attended Jennifer’s birthday party in Las Vegas in July and shared a number of clips of them together at the bash on Snapchat.
He split up with Taylor Swift, 26, a few months ago, while Jennifer – who has eight-year-old twins Max and Emme with her ex-husband Marc Anthony – and her backing dancer Casper Smart recently ended their on/off relationship.
