The couple have parted ways this weekend and have called off their engagement also.
According to sources the young couple felt that they were not ready to make that kind of commitment to one another as they are both so busy right now.
The pair has been inseparable since they got engaged in May after Davidson lavished the singer with a $100,000 diamond ring.
And they have been photographed out and about in New York looking to be very happy with one another.
However, Grande expressed via social media that she was having a difficult time recently while she called off several appearances too.
She hinted that she wanted to step away from the spotlight.
One Tweet read: "Can i pls have one okay day. just one. pls."
Davidson has been a constant on SNL and it is understood that the pair have remained friends and that they could still get back together at a later date.
RadarOnline.com reported recently how Grande had been suffering from anxiety following the death of her former boyfriend Mac Miller.
