"Pauly and Aubrey have split, for good this time," the source explained. "Pauly was the one to end things."
"Aubrey was pressing Pauly for an engagement ring," the source added. "Pauly did not see marriage with Aubrey in his future."
The Jersey Shore star, 37, and the former Danity Kane member, 33, were still together as of June, when they were filming the after-show for the current season of Famously Single. As fans of the former couple know, the two met on the set of the reality series in November 2015.
Since the split, it appears Pauly has removed all pics of the singer, with the exception of a Famously Single cast photo. Aubrey's account still features photos of the Providence, Rhode Island, native, the last being a gif of the two inside a photo booth for her birthday in February.
Aubrey doesn't seem fazed by her ex's move, however. She posted a sexy shot of herself, clad in a black one-piece, on Tuesday, captioning it, "Voices in my head sayin' I could do better, damn."
