Dressed in skinny jeans, Converse trainers and a grey T-shirt, Kristen, 21, and her canine companion braved the wind and rain as they made their way across New York's East Village.

The young actress was still in the Big Apple after attending the annual Met Gala on Sunday evening, where she looked sensational in a red and black Proenza Schouler halter neck dress.

Clutching his blue lead, Kristen was careful to keep a tight hold on Bear as they set out across the city together.

Pattinson found Bear in an animal shelter while shooting Breaking Dawn in the Baton Rouge area of Louisiana.

The dog was originally called Yogi Bear, but Pattinson and Kristen decided to shorten his name to Bear after Rob admitted he thought Yogi was 'a bit much.'

Kristen, and her canine companion, have been staying at one of the actress's favourite New York hotels, The Bowery, on the Lower East Side of the city.

Along with Dakota Fanning she hosted an after party at the hotel in March 2010 to celebrate the release of their movie, The Runaways.
