But the film’s mega-success has brought pain to the British actress’s life as well.

During an interview to promote the release of “Titanic” in 3D, Winslet revealed that — near, far, wherever you are — she really doesn’t want to hear or perform the film’s theme “My Heart Will Go On.”

At least, that’s what I think Winslet meant when she told MTV that hearing the song makes her feel “like throwing up.”

She quickly continued, “No, I shouldn't say that. No, actually, I do feel like throwing up.”

The thought did not end there: “I wish I could say, ‘Oh listen, everybody! It's the Celine Dion song!’ But I don't. I just have to sit there, you know, kind of straight-faced with a massive internal eye roll.”

To be fair, it seems that the song has kind of haunted her since it became a gigantic hit 15 years ago. Winslet told MTV an Italian talk show asked her to sing the song during a recent appearance: “It was like, ‘No! I'm not going to do that.’ They're like, ‘Oh no, come on it will be funny.’ No, it won't be funny. At all. And I'm not going to.”

Apparently feeling like she could open up quite a bit to MTV, Winslet also shared her feelings about her performance in “Titanic,” as the love-sick Rose. “My American accent could have been much better, my acting could have been a lot better and I think I look nicer now,” she explained.
