The 36-year-old actress thinks the tables have turned since the 1997 blockbuster.
"We do look very different, we’re older. Leo’s 37, I’m 36 – we were 21 and 22 when we made that film. You know, he’s fatter now, I’m thinner. It’s true though," she said jokingly on television show "Daybreak".
With the movie having been re-released in 3D to mark the 100th anniversary of the Titanic tragedy, Kate admits it has been weird to come face to face with her younger self, reports contactmusic.com.
"I put my glasses on and I sat there all excited and then the second my face came on, I was like, ‘Oh my god, make it stop, switch it off, somebody make it stop, turn the sound down, is that what we looked like? Oh my God, look what I looked like and look what Leo looks like," she said.
But the actress has decided the time is right to let daughter Mia, 11, and son Joe, 8, watch the film in it’s entirety, nude scene included.
