Matt Damon awarded 'surprise' honour at UNICEF Ball

Matt Damon was left speechless when he was awarded a surprise honour at the UNICEF Ball in Beverly Hills, California on Tuesday, after paying a tribute to his 'Behind The Candelabra' co-star Michael Douglas.

The 43-year-old actor helped to host the event and presented Douglas with Danny Kaye Humanitarian Peace Award, but had no idea that he'd be taking home a prize too, Contactmusic reported.

At the end of the ceremony, Damon was presented with a trophy to recognise his work with clean water and sanitation charity water.org.
