The 'On The Floor' singer has reportedly cooled down her romance with the 'Hotline Bling' hitmaker but the pair aren't ruling out making another go of it "in the future".

A source close to Jennifer told Entertainment Tonight: "She likes Drake. They're just busy, so it has fizzled.

"She's a mom with an insanely busy career. He's touring in Europe. Who knows what will happen in the future when they're more able to be in the same place."

It comes after it was revealed the couple have decided to "take some time apart" but are still very much "in each others' lives".

A source said: "They have taken some time apart, not because they don't want to be with each other, just because their schedules started getting insane.

"JLo and Drake are still talking, so people should know they are not in any means angry or that some incident happened. It mainly had to do with timing. They have just cooled things off a bit and it's not as fast as it was in the beginning. They very well may go to dinner tomorrow or in a month. They are in each others' lives, just doing their own thing now."

It is thought the 47-year-old singer - who has eight-year-old twins, Max and Emme, from her marriage to ex Marc Anthony - was alluding to the couple's split when she posted a cryptic Instagram quote over the weekend.

She wrote: "Timing is everything. If it's meant to happen, it will, and for the right reasons."

The pair are said to have become close whilst working on music together late last year.

A source said at the time: "They do work on music together [but are] clearly enjoying each other on another level too. Jen loves the attention and she seems very happy to be spending time with him. Drake is very charming. He treats Jen with lots of respect. She seems very smitten."
