Demi Lovato "mostly a lock" to return to 'The X Factor' USA

Demi Lovato is poised to return as a judge on The X Factor USA, it has been reported.

According to HollywoodLife.com, the 20-year-old singer will almost certainly be reprising her role on the Fox talent show.

A source said that Lovato is "mostly a lock" to return to the programme, and that it is also "most likely" she will share the stage with girl group Fifth Harmony for a live performance on an episode.

In addition, Lovato is also likely to appear on a Fifth Harmony single. The band took third place in the competition last season and were mentored by Simon Cowell.

The 'Skyscraper' singer has previously said that she is "always open to collaborations" and "would like to show these girls a 'thank you', and show them how much they have done for [her]".
