Jennifer and Vince met on the set of romantic comedy 'The Break-Up' shortly after Jennifer was dumped by ex-husband Brad Pitt for Angelina Jolie. During their time together Vince and Jennifer continually denied they were an item but then moved in together in Chicago and there were rumours of a proposal in June.
