She revealed: "We filmed five months in London. I'm so used to living in Los Angeles that I loved being in a big city. London is wonderful, especially if you like steak and kidney pie."
Kristen is currently travelling the world promoting the movie - which also stars Charlize Theron and Chris Hemsworth and is based on the classic Brothers Grimm fairytale - and although she enjoys the trips she hates having to wear gowns on the red carpet.
The 'Twilight' star - who is due to attend the Cannes Film Festival this week - is known for her alternative fashion sense and she doesn't enjoy having to get dressed up for the cameras.
In an interview with the New York Post newspaper, she said: "We're doing Cannes, and then there's the screening in New York on May 29 and the opening June 1. That means gowns. I hate gowns so much. Just wear them once and give them back. After the opening, I go home."
The other thing that Kristen hates about being away from her home in Los Angeles is that she has to leave her two pet dogs behind, and she is always desperate to see them by the time she returns to the US.
She said: "Now I only want to be with my boys. I'm dying when I'm away from them. My two mutts. A yellow Lab and a shepherd. I can't stand it. They're what I miss."
