The Sherlock Holmes actor has announced his engagement to fellow actor Sophie Hunter in a classified advert in The Times.
The announcement reads: "Mr BT. Cumberbatch and Miss S.I. Hunter: The engagement is announced between Benedict, son of Wanda and Timothy Cumberbatch of London, and Sophie, daughter of Katharine Hunter of Edinburgh and Charles Hunter of London."
The 38-year old actor who is also the voice of Smaug the dragon in the Hobbit trilogy has kept his relationship with Hunter, 36, out of the media until he made this traditional announcement in the Birth, Deaths and Marriages section of The Times.
