"There was no bad blood and no third party involved. It was honestly just a long distance relationship and it became too hard to make it work," the source explains. "It's not necessarily forever and they could get back together. Nobody is to blame. Just the distance."

The pop star, 28, and the Boardwalk Empire star were first linked back in June 2011. By September, Simpson had already met NYC native Piazza's parents. (The group hung out together at the Emmy Awards that year.)

"She's a wonderful girl," Piazza told Us earlier that month during the premiere of his HBO hit.
