American singer Jewel has taken part in a prank for comedy website FunnyOrDie.com

As part of the undercover karaoke stunt, Jewel was transformed in to the mild mannered office worker Karen – the process involved putting on a fake nose, wig, glasses and a very frumpy suit!

‘Karen’ AKA Jewel was then accompanied by her fake co-workers and an undercover film crew to a Los Angeles karaoke bar where she proceeded to belt out two of her hits ‘Who Will Save Your Soul’ and ‘Foolish Games’ to an amazed crowd.

It’s all been caught on video and was posted on the FunnyOrDie website on Tuesday and has reportedly had over 160,000 views as of Tuesday evening… watch it below and find out why it’s got everyone talking!
