The volatile couple is currently spending time with one another and their baby girl Ariana Sky in Puerto Rico.
The news comes after Harley was infamously jailed for a road rage incident involving the reality star.
An insider revealed: "They've been quiet about it but it's been about a month now.
"They want peace and they want things to work our for the baby's sake."
"There was so much up and down with them, so much drama, and the cameras caught a lot of it."
RadarOnline.com previously reported how the Jersey Shore star and Harley had a major bust-up following a road rage incident while she was once busted for a public threesome.
However, it appears they have become close again, on Friday they posted an image together via Instagram Stories.
