"If I was friends with Bella I'd be like, 'Please make life easier and date Jacob,' " she said at a New Moon fan event in London Wednesday – where 2,000 admirers screamed.
But as for Bella herself? "I'd make her a vampire," Stewart, 19, said.
In real life, Stewart would opt for something infinitely more mundane, if she ever got a month off from Twilight madness, that is. "I would go home and do nothing," she said. "I know that sounds really boring but all I want to do is do nothing."
Though Pattinson, 23, dodged questions about his alleged relationship with Stewart by calling reports "speculative," the leading man said becoming a Hollywood dreamboat has changed his life for the better.
"The paler you are, the better you do with women," he said. "Becoming essentially a sex symbol, being English, you realize you can break a bunch of molds that I don't think many people realize you can – you don't need to go to the gym or anything!"
But would London-born Pattinson arrange a meet-up between Stewart and his folks by arranging for a sleepover with his costars at his family home?
"Oh no," Stewart said.
