Teen wolf Taylor Lautner has confessed that he found it difficult carrying co-star Kristen Stewart while filming a scene on the set of The Twilight Saga: Eclipse.

Taylor said that despite her being really light, it was tough carrying the actress around. "There's a scene where I'm carrying Kristen, and it's also, like four pages of dialogue,"  he said. "We actually had plans, a rig that was basically going to carry her, and I was just going to pretend that I was carrying her. We got there on the day, and the rig didn't look very natural. They were like, 'What are we going to do?' and I'm like, 'I'll just carry her. She's like, what, 110 lbs? It's no big deal!'

We filmed that scene all day long, did the wide shot, did my close-up, did her close-up, the back shot, everything. It was so hard. ... It was painful."

Another on-screen challenge for Taylor was having to be mean to fellow lead actor Robert Pattinson.

He said: "I had a scene or two in New Moon where I was able to work with Rob, and I was really excited to work with him for Eclipse. The hardest thing I found about working with Rob is I usually have to hit him in the scenes, and it is difficult.

"He is such a funny, nice guy. It is literally like we are doing a scene where we are yelling and screaming at each other, and he is slapping my shoulder and I'm shoving him off me. We are screaming. We are spitting in each other's faces. Then as soon as they call, 'Cut,' we just bust out laughing. It is really hard to be mean to Rob."

OMG… we are getting so excited for Eclipse!
