Leo’s response to this little girl’s selfie request is adorable

This young fan just got the selfie of a lifetime...

 It’s not everyday you end up sitting next to one of your Hollywood heroes. But if it does happen, it’s obvious what you do – ask for a selfie.

Which is exactly what one girl did when she spotted Leonardo DiCaprio at the U.S. Open. Leaning over the dividing wall between them, she asked the Oscar-winning actor for a selfie – which he willingly obliged. In fact, Leo even checked whether the girl was happy with the photo afterwards in what we reckon must be the selfie of a lifetime.

The Oscar-winner was watching the Men’s final of the U.S. Open at Flushing Meadows in New York, where Stanislas Wawrinka beat Novak Djokovic to win the championship title.

And while Leo was on one side of the section barrier with Israeli investor Vivi Nevo, one of his fans was sat on the other. Evidently, despite Leo’s attempt to remain under the radar in casual jeans, shades and a flat cap, it wasn’t a sufficient disguise to fool his young fan.

This appearance comes just a few days after Leo walked the red carpet at the Toronto International Film Festival.

The actor was at the festival to premiere of his film Before The Flood – a documentary about climate change and the threat it poses to our planet.

Leo is a long-time environmental campaigner as well as being a UN Ambassador of Peace. In the documentary, he travels around the globe to highlight the damage climate change is causing, from the toxic tar sands in Alberta, Canada to the smog-cloaked city centre of Beijing.

One of the most troubling scenes comes in the form of the scorched land in Indonesia – a result of forest fires caused by the unsustainable palm oil industry.

Sound interesting? Before the Flood will be aired on the National Geographic Channel from 30th October.
