Kate Winslet carrying her daughter Mia on her back in New York, USA - 220404

Winslet didn't have the heart to explain that 'Uncle Leo' was actually a megastar called Leonardo DiCaprio.

The British actress recalls, "There was a picture of Leo on the front of a newspaper and Mia picked it up and went, 'Mum, it's Leo, he's on the cover of the newspaper. We should really keep this and send it to him, mummy."
