WATCH: The Chainsmokers made a fan's day by bringing her on stage to sing 'Paris'

The Chainsmokers are currently on tour in the US and totally made this fan's day when she was invited on stage to sing their hit 'Paris'.

YouTube singer Nicole Starr is a massive Chainsmokers fan and wanted to see if she could get on stage with them when they came to St Louis. Asking her online following to try to arrange for her to sing on stage, she asked them to DM the DJs.

Although she probably didn't expect it, Andrew and Alex, better known as The Chainsmokers surprised the teenager as they stopped their performance and asked for her by name saying,

"Earlier when I was on the bus I was checking my phone and all these DMs started coming in about bringing this girl on stage in St Louis to sing a solo.

"Is Nicole Starr here?"

Nicole was then brought on stage where she wowed the DJs and their fans with her performance of 'Paris'.

The DJ duo were so blown away by her performance they shared their excitement by tweeting how it came about saying, 'Such a cool thing happened tonight!'

Nicole has since uploaded a video of her performance on stage including clips of her meeting the group backstage, on her YouTube channel.

The Chainsmokers continue their US tour of Memories Do Not Open and will be making some festival appearances this year in the UK.
