Not only were the young stars of Stranger Things the snappiest dressers at last night's Emmy Awards, they also rocked the audience with a fantastic performance.

Millie Bobby Brown, Caleb McLaughlin, and Gaten Matarazzo performed the Bruno Mars and Mark Ronson hit track 'Uptown Funk'.

The biggest winner was Game Of Thrones. The HBO epic swept the boards at the Emmys, claiming 12 gongs to become the most honoured show of all time.

Watch Millie, Caleb and Gaten from Stranger Things perform below.
