Stewart has reportedly split from longtime boyfriend Michael Angarano, paving the way for a romance with her movie love interest Pattinson.

The media has been linking the Twilight twosome ever since they first appeared onscreen together in last year's vampire love story, and the romance reports went into overdrive when the pair started shooting the sequel New Moon in Canada.

Both Pattinson and Stewart have denied they're anything but close friends and co-stars, and the British actor's aunt Diana Nutley hopes it stays that way - and the love rumours are false.

She tells U.S. magazine Life & Style, "I don't think it would be a good idea for Robert to be in a serious relationship with Kristen. How can he live his life with a fellow star, with their every move being watched just like Tom Cruise and Katie Holmes?"

And Nutley, who is the sister of Pattinson's mother, hopes her famous nephew will make the most of his overnight super fame - and have fun.

She adds, "He's only 23 and probably won't get married until he's 40, if he's got any sense."

And she hopes he'll eventually settle down with an English girl: "I think he will eventually come back home to England and fall in love with somebody he's known since school."
