Is Kate Winslet pregnant? The internet thinks she might be.

Is Kate Winslet pregnant with her fourth child?

The rumours are swirling after she was spotted chatting with fellow actresses Brie Larson and Cate Blanchett at the Oscars yesterday.

While chatting as a group, an ecstatic-looking Blanchett was seen gently touching Winslet’s stomach, leading some to speculate whether that was the moment the Titanic star revealed she was expecting.

Sure, it could have just been a tender moment between three friends - but social media almost immediately lit up with rumours that Winslet had just announced some very happy news.

The 40-year-old already has three kids - Mia Honey Threapleton, 15, with ex-husband Jim Threapleton, Joe Alfie Winslet Mendes, 12, with ex-husband Sam Mendes, and Bear Blaze Winslet, 2, with current husband Ned Rocknroll.

Larson ended up winning the Best Actress trophy for her role in Room, while Blanchett had been nominated for her performance in Carol. Meanwhile, Winslet was a Best Supporting Actress nominee for Steve Jobs.

We don't want to speculate - but the photos did seem to capture a special moment between the three Hollywood heavyweights...
