Model Holly Madison has split from musician Jack Barakat after a 10-month romance.
The stars met on and went public with their relationship at the former Playboy Playmate's birthday party in December (10) - but they've now decided to part ways.
A representative for Madison, who once dated Hugh Hefner, tells E! Online, "I can confirm Holly and Jack are no longer dating. Their decision to split was both mutual and amicable."
