Movie premieres makes Kristen Stewart hyper
London: Actress Kristen Stewart says she becomes hyper after the premiere of her movies.
"By the end of the day I actually get really hyper, because it`s then that I have my own time. You end up staying up all night and then screwing your morning the next day because you need time to yourself," a news website quoted Kristen as saying.
Kristen is busy promoting her upcoming movies. She appeared at the Los Angles premiere of "The Twilight Saga: Eclipse" Thursday and new drama "Welcome to the Rileys" Friday.
