The 38-year-old actress is expecting her third child -- the first with new husband Ned Rocknroll -- at the end of the year. She already has a daughter, Mia Honey, from a first marriage to Jim Threapleton, and son, Joe, from her second marriage to director Sam Mendes.
"At the moment I seem to be wanting orange juice a lot," Winslet told US Weekly at London's Leicester Square. "I don't know quite why that is, but it's not so weird. I wish I could tell you I had some weird craving. I wish I could be like that woman on the advert who loves tuna fish and banana, but I'm not like that at all."
Winslet and her "Labor Day" costar Josh Brolin have garnered Oscar buzz for their performances in the film, in which a single mother and her son spend the holiday weekend with an escaped convict. But the actress said pregnancy has kept her occupied.
"It hasn't even crossed my mind, I'm so absorbed in baby," Winslet said of this year's awards season. "[It's] is always a huge amount of fun whether you're a part of it or not. It's always really exciting seeing what films are coming and a lot of new talent as well."
