Geographical incompatibility was blamed for Ashlee Simpson's breakup with "Boardwalk Empire" actor Vincent Piazza. "There was no bad blood and no third party involved," a source told Us Weekly. "It was honestly just a long-distance relationship, and it became too hard to make it work. It's not necessarily forever, and they could get back together. Nobody is to blame. Just the distance." Ashlee first stepped out with Vincent in June 2011, a few months after her two-year marriage to Pete Wentz fizzled. "It was a mutual agreement to split," an insider added to the New York Post, "but things have been bumpy for a little while, so perhaps they might reconcile."
