Kate Winslet became a household name in 1997 with the release of James Cameron’s epic movie based on the sinking of the infamous Titanic.

But appearing on ITV1’s Daybreak, the 36-year-old star seemed more concerned with the shape of her body than the mega ship itself, despite the centenary of its demise being commemorated this year.

The actress, who sported diamond earrings to the London premiere of Titanic 3D, described the horror she felt at facing more than three hours of her 21-year-old self on screen in the Oscar-grabbing blockbuster.

She told presenter Kate Garraway: “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.”

The star was making a good-natured joke and added that she wanted to switch off the movie because she was so struck by how both actors looked.

She added: “Oh my God, look what I looked like and look what Leo looks like!”

Winslet is set to appear in a string of movies out next year, including The Guernsey Literary and Potato Peel Pie Society.
