Benedict Cumberbatch is now engaged to girlfriend Sophie Hunter. News of the engagement was revealed in the "Births, Marriages and Deaths" section of The Times newspaper.
When asked about their romance in the summer, Sophie's mother Katharine said: "Watch this space."
The pair was last seen at London restaurant Quaglino's, but the two arrived separately and were keen not to be photographed together.
They first met when starring opposite one another in 2009's Burlesque Fairytales.
Just a year ago the Sherlock star insisted he wasn't in a hurry to get married.
He said: "It's a wonderful thing to get married young and become a father. I used to think that I'd get married by my mid-thirties and have children. But now I think I can wait. I'm no longer in a hurry to get married."
