Benedict Cumberbatch will permanently be taken off the market TOMORROW.

The Sherlock star will wed fiancée Sophie Hunter on Valentine's Day in a ceremony in front of close friends and family on the Isle of Wight.

Benedict, 38, and 36-year-old actress Sophie announced news of their engagement in the births, marriages and deaths section of The Times back in November.

The Sunday Mirror revealed the pair were dating back in September, after they met on set of 2009 movie Burlesque Fairytales.

Last month, the couple revealed they are expecting their first child together.

Benedict said a year ago he was in no hurry to get hitched, explaining: "I used to think that I’d get married by my mid-30s and have children. But now I think I can wait."

Clearly, not so long.

Yesterday, workmen were erecting a marquee and several white tee-pee tents in the grounds where the pair will tie the knot in a romantic Valentine’s Day wedding. A nearby road will be closed off for the occasion.

Benedict is in the running for the Leading Actor award at next Sunday's Academy Awards for his role in The Imitation Game

His fellow Oscar-nominated Brit pal Eddie Redmayne tied the knot with wife Hannah Bagshawe in December last year, and returned from honeymoon at the start of the awards season - promising a second, longer break later in the year.

Benedict and Sophie are expected to go on honeymoon in the immediate future.

When the engagement was announced, Sophie’s delighted mum Katharine said: "We are very happy for them. It’s a really fabulous day.

"It's only just been announced we don’t know any more but it's lovely news."

Sophie's brother Patrick, 30, added: "We're all very happy for Soph - it's really exciting."

Asked to describe his ideal partner, Benedict has said: "A woman who knows that she doesn’t have to get all decked out to look good is sexy. A woman who can make you feel smart with her conversation skills is also sexy."

Benedict previously dated London artist Anna James, in 2012, and dated actress Olivia Poulet for 12 years.

Sophie's film and TV credits include roles in Torchwood and Midsomer Murders.

Congrats, guys.
