Kristen Stewart, who has been rumored to be dating Robert Pattinson since they started working together on the Twilight Saga, can make her British leading man "uncomfortable".

The actress is known for speaking her mind, which can sometimes lead to awkward situations. The 24-year-old actor, meanwhile, confessed he is not able to be as vocal in his opinions.

"Kristen is always really good but also clearly speaks her mind. That can be a bit uncomfortable," Robert told Germany's Sächsische Zeitung newspaper.

"After we shoot a scene she sometimes looks at the director and says, 'Let's do that again.'

"If I did that she would probably kill me! She would probably say something like, 'Shut up! The scene was perfect!' "

Robert, who is constantly travelling because of work, reveals there is no longer any place he can call home.

"My home consists of three suitcases which I live out of," he said. "Everything is in there."

In line with this lifestyle, the heartthrob gets his food specially-prepared and sent to him.

"In Los Angeles I started using a delivery service which only delivers fresh and healthy food. Even in the morning I have a bag with healthy food delivered to me. I've never in my life lived as healthy as I do now," he said.

"Of course I miss homemade food, but I'm on my own or on the go most of the time. And I can't cook myself. I only just manage to make some toast. I don't seem to have the genetic endowments for it. I'm incapable to tell what tastes good and what doesn't."
