The two acts were in the final showdown of last year's X Factor, with Burke's soulful voice beating heart-throbs JLS to the prize.
In the meantime, both have gone on to top the charts, Burke with her cover of cover of Leonard Cohen's Hallelujah and the boys' debut single Beat Again rocketed to number one last month.
Beat Again also features in the best song category.
Former Eurovision contestant Jade Ewen is also in the category, as are Irish soul singer Laura Izibor and London-based MC Master Shortie.
Alesha Dixon, who is joining Strictly Come Dancing following the departure of Arlene Phillips amid an age row, is in the best UK act category.
The category only features two women - Dixon and Beverley Knight.
They will battle it out with Dizzee Rascal, Tinchy Stryder, Bashy, Chipmunk, DJ Ironik, Donae'o, Mr Hudson and N-Dubz.
Dixon is also up for a video award for her hit Boy Does Nothing.
Knight is up for best r&b/soul act, vying with Lemar, Keri Hilson, Jeremih and Ciara.
