The pop star is claimed by HollywoodLife.com to be "almost certain" to reprise her role on the reality TV show - which has seen the departure of Britney Spears and LA Reid.
And the showbiz gossip site also claims that 20-year-old Demi is "most likely" to record a collaboration with Fifth Harmony, who she performed with on last year's show.
She has previously said that she "would like to show these girls a 'thank you', and show them how much they have done for [her]".
The site also claims that boy band Emblem3 and series winner Tate Stevens are being lined-up to perform on this year's series.
