Amber Riley has appeared on US talkshow Jimmy Kimmel Live to perform a moving tribute to her Glee co-star Naya Rivera.

The actress died by drowning in July while swimming in a Californian lake with her young son, whom she helped to safety in her final moments.

Riley, who starred alongside Rivera for all six seasons of the FOX show and became close friends with her in real life, performed her forthcoming single 'A Moment' in tribute to her on Thursday night's episode of the show.

Pictures of Rivera were projected in black and white behind Riley, who turned to face her image at the end of the song.
