Liv Tyler is rumoured to be dating Benedict Cumberbatch.

The Armageddon actress was spotted on a date with British star Benedict at a cinema in Hollywood on Tuesday night.

British newspaper The Daily Mail reports the couple attempted to disguise the fact they were enjoying an intimate evening out together. They failed to remain undiscovered as they strolled out of the ArcLight Cinema on Sunset Boulevard after the movie.

It was reported earlier this year that Benedict and Liv would both be appearing in the movie adaptation of Scott Organ's play Phoenix.

Phoenix tells the story of a couple who have to deal with the circumstances following a one-night stand together.

As well as their rumoured attachment in the upcoming independent film, the two stars seem to have grown close at last weekend's Emmy Awards.

On Sunday night, 35-year-old Liv and Benedict were both spotted at party held at the Sunset Tower Hotel after the ceremony.

While they left the event separately, they were reportedly seen together inside.
