'They still talk and there has not been a defining reason behind it, just that it's becoming more difficult to maintain the relationship between the distance and both their schedules,' the insider told the outlet.

'They have not made an announcement because I don't think they know what will happen and could just as easily resume come the summer,' they added.

The couple had been dating for 18 months, having met in Los Angeles five years ago.
