Kate Mara and Max Minghella have split after a four-year relationship, according to a U.S. report.

The House of Cards actress and the British actor have been dating on and off since 2010 but have now called time on their romance, according to Usmagazine.com.

A source tells the website, "Max and Kate have broken up and gotten back together a few times over the course of their relationship, but this one looks like it's sticking...The relationship just ran its course."

Mara attended the Emmy awards on Monday (25Aug14) without the Social Network star.
