I saw your advert in the paper <a href=" http://www.poly.ee/polygon/#weird ">dermatologist bimatoprost</a> Ashlee Simpson and "Boardwalk Empire" star Vincent Piazza are together no more. After 18 months of dating, the couple is citing distance as the reason why their relationship has come to an end, Us Weekly reports. "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," a source told the gossip mag. Simpson, mom to 4-year-old son Bronx with ex-husband Pete Wentz, hit it off with Piazza in June 2011.
