As many of his fans already know, Tom Hardy is a huge fan of dogs.

So it was no surprise to see the bearded actor out and about walking his pooch Cass around West London last week.

The British star kept a low profile for the outing as he wore a grey End Of The World top and beige trousers, teamed with black and grey trainers.

Puppy love: Bearded actor, Tom Hardy, was seen out and about walking his pet pooch Cass around West London last week

The 37-year-old completed his look with a camouflage union jack baseball cap and several bracelets.

Animal lover Tom's other dog Woodstock (or Woody, as he's more affectionately known) was a regular fixture on the London set of Tom’s recent project, gangster film Legend, where Hardy plays the characters of both Ronnie and Reggie Kray.

The movie, set and filmed in London's East End, follows the rise of the Kray twins during the Sixties and the criminal activities that led to their arrest on May 9, 1968.

During his time as the top crime boss in the capital, Reggie married Frances Shea - played in the film by Emily Browning.

Ronnie and Frances married in 1965, at St. James’s Church in Bethnal Green, but after a week’s honeymoon in Athens she was sent to live with her mother.

Frances was the younger sister of Frank Shea, a childhood friend of the Krays, and she began dating Reggie when she was 16-year old before he was locked up in Wandsworth prison for 18 months for protection-related threats.

It was alleged that Reggie murdered his sister-in-law which was made to look like suicide.
