The 'Change Your Life' hitmakers and the 'Swagger Jagger' singer will join forces with 'The X Factor' USA judge on her 2014 tour 'The Neon Lights', which will kick off in Vancouver in February before concluding in the US in March.
Demi took to Twitter to share the news, posting: ''So excited that @LittleMixOffic @FifthHarmony and @CherLloyd will be joining me on #TheNeonLightsTour!!! #GIRLPOWER (sic).''
The 20-year-old rapper - who shot to fame on 'The X Factor' UK in 2010 - is no stranger to working with the 'Heart Attack' singer after the pair collaborated on her album 'Demi' earlier this year.
Cher said previously: ''I think me and Demi are in some ways kind of similar. We have quite a young fanbase and this is very much a girl power song. You know, it has a great feel to it, and I'm so excited that people get to hear it now.''
There are currently no plans for Demi to tour outside of north America as of yet.
This Doctor won't be saying 'goodbye' in the same way as those who have left the series in recent years.
