Liv Tyler has sparked rumors she's dating British actor Benedict Cumberbatch after the pair was spotted enjoying a trip to the cinema.

The Lord of the Rings beauty has been largely single since splitting from British rocker Royston Langdon, the father of her son Milo, in 2008 after five years of marriage.

She has now sent gossips into a spin after enjoying a movie date with War Horse star Cumberbatch in Los Angeles on Tuesday night.

The hook-up comes two nights after the pair attended the same post-Emmys party at the Sunset Towers hotel in West Hollywood on Sunday, where they were spotted chatting to the Cumberbatch's Star Trek Into Darkness co-star Zachary Quinto.
