Sandra Bullock has laughed off rumours that she is dating Captain America's Chris Evans, joking that they have since married, and are now filing for divorce.

The Gravity star was spotted having dinner with Evans in Los Angeles last month, but Bullock told Entertainment Tonight: "I'll tell you what happened. We've since married."

Bullock continued: "And it just started breaking apart and now we're filing for divorce. And I hope everyone can respect our privacy.

"But we're gonna remain friends and share the responsibility of the farm animals we've taken on, because you can't just abandon farm animals."
