The split decision was made because the couple was no longer able to endure a long-distance relationship, reported E! Online.
“This has been a sensitive matter and both of them still love and care about each other and only want the best for one another.
The long distance and ups and downs have been weighing on the two of them lately and it has not been easy but they know this is the best decision for them at this time,” a source said.
Jonas, 22, and Culpo, 23, sparked break-up rumours last week after they were spotted in New York City but staying in separate hotels.
