“House” star Olivia Wilde has called Robert Pattinson is like a “frog in boiling water” in comparison to her slow rise to fame, and questions whether the “Twilight” hunk’s time in the spotlight will last.

The Irish-American actress, and Maxim’s sexiest woman of the year, says in the October issue of GQ that while she has slowly but surely gained star status, the English actor became an international superstar overnight – which isn’t a good thing.

“I did not envy him,” Wilde, who recently hung out with Pattinson, says. “I think it’s the frog-in-boiling-water concept. Robert Pattinson jumped in boiling water and has stayed in it, and hopefully will survive.

“Whereas I entered the water when it was cold, and it’s been slowly heating up — a slooooow boil. Maybe I won’t realize when it’s getting dangerous.”

Wilde, who stars in the upcoming critically acclaimed indie film “Fix,” goes on to explain that she can sense that she’s much more famous than she was just two years ago when she joined the cast of the hit TV series “House,” and finds it funny that she’s considered a sex symbol.

“I’m definitely at this point now where things are shifting, they’re changing very fast,” the actress, who has dual citizenship in the U.S. and Ireland, says.

“The only role I really don’t understand is this recent sort of ‘sexiest vixen’ thing. It doesn’t feel like me, doesn’t feel natural.”
