Kate Winslet poked fun at her "Titanic" co-star Leonardo DiCaprio, joking about the actor's weight.
"We do look very different, we're older," Winslet told iTV's "Daybreak" while promoting the film's 3D re-release. "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 actress has been open about her weight struggles and the fact that kids called her "blubber" when she was a child. She told Glamour magazine in March that she maintains her weight with running, workout DVDs and Pilates.
DiCaprio recently gained weight for his Oscar-nominated role as J. Edgar Hoover in "J. Edgar."
"I had a lot of weight on me... I kept adding this weight just because I wanted to feel the weight of the country and the world on his shoulders," DiCaprio told the Associated Press. "I just kept feeling more and more claustrophobic, and I tried to use that for the character, because I felt like he felt more and more claustrophobic in his position."
Both Winslet and DiCaprio have said they were embarrassed to watch themselves in "Titanic in 3-D," which opens in theaters on April 4, 2012.
"The second it came up I literally went, 'make it stop, make it stop, turn it off. I'm blocking it off. Do I really sound like that? Did I really look like that?' It's very, very bizarre," Winslet told iTV. "It's like someone saying, 'OK here's a home video we made of you 16 years ago and now we're gonna make you watch yourself in 3-D.'"
Director James Cameron said that DiCaprio had a similar reaction, squirming through a screening of the film.
"I didn't show him the whole film but I showed him 18 minutes of it a few months ago." the photo agency WENN quoted Cameron as saying at the film's premiere. "It was a good reunion for us but great to watch his reaction. He couldn't believe it. He said to me, 'I'm such a young punk. Look at me.' He was practically crawling under the seat. It was a good moment."
DiCaprio didn't attend the worldwide premiere of "Titanic 3D" in London on Tuesday, March 27, as he was in Louisiana shooting Quentin Tarantino's film "Django Unchained," but Winslet and Cameron held down the red carpet.
The movie, which won 11 Oscars, is one of the highest grossing films of all time. The premiere of the 3-D re-release marked the 100th anniversary of the ocean liner's tragic maiden voyage on April 1912.
