Hollywood star Kate Winslet can't watch herself naked in 3D.

The British actress turned up to celebrate the release of Titanic 3D at London's Royal Albert Hall, but admitted she wouldn't be staying to see the intimate scene between her and Leonardo DiCaprio's character.

Asked how she would feel seeing herself nude on the big screen, she responded: "Terrible, wouldn't you? I'm not going to look, I'll be in the bar by that point."

Kate - who played the role of Rose DeWitt Bukater in the romantic movie based around the sinking of the iconic cruise liner in 1912 - added it would be strange to see herself back when she was younger.

She said: "It is like being forced to go through a photo album of your former self for three and a half hours solidly.

"It's quite strange but the film is still wonderful and it looks incredible. I haven't seen the whole film in a very long time, I've seen little pieces of it, but it's a whole different me and we look much younger and our acting was different, hopefully not as good as now."

Others to walk the red carpet at the event included the movie's director James Cameron and co-star Billy Zane.

Titanic 3D is released in New Zealand on April 5.
