After three and a half years together and a professional relationship prior to that, Britney Spears and her fiancé Jason Trawick have called it quits.

Spears began dating her then-agent in 2009, and since then, the couple got engaged and Trawick even became a co-conservator in the pop star's estate. But they announced late Friday (January 11) that they "mutually agreed to end their one-year engagement."
