Filming on the vampire franchise in which Robert plays vampire Edward Cullen wrapped in April and the star is glad he doesn't have to stand half naked next to Taylor Lautner - who played his character's love rival, werewolf Jacob Black - to film scenes anymore.
He said: "I had to take my shirt off next to Taylor. I'm sure you all know what a superb specimen that guy is. He makes me look like such a wimp."
While he will miss his character's personality, Robert is glad to be rid of the particularly uncomfortable eye lenses he had to wear for his character.
He added to Look magazine: "I won't be missing (wearing) the contact lenses, they were painful. But I liked how understanding Edward was, that he was Old School. I will miss that."
Robert - who is in a relationship with his 'Twilight Saga' co-star Kristen Stewart - previously admitted he had to be held down so the make-up artists could insert the lenses because as couldn't physically do it himself.
He said: "Everyone else has figured out how to do it, and then there's two people holding me down because I can't do it myself. It's so embarrassing for me, after so many years, it's still a process every single morning - I want to kill them."
'The Twilight Saga: Breaking Dawn - Part 1' is released on November 18.
