Charlie Lenehan and Leondre Devries, who took the nation by storm earlier this year with their anti-bullying song 'Hopeful', will be performing at the Voice In A Million concert.
And joining the BGT stars on 11 March 2015 will be X Factor's Overload Generation!
Overload Generation made it through to the live shows of this year's ITV talent show, but unfortunately they became the second act to be voted off the show during the first week.
However, the boyband are now gearing up for their massive arena performance ahead of the release of their new single 'No No No'.
Fans of either acts will also know that BAM's Leondre is the younger brother of Overload Generation's Joseph - it's a right family affair!
The music extravaganza will see a mass choir of 6800 school children from all over the UK united in song to raise awareness of the plight of children in care both at home and abroad.
Voice In A Million was set up by adoptive parents, Jo and Robert Garofalo, in 2009. Now in its fourth year, the concert aims to raise awareness of children and youngsters in orphanages, institutions or care. Celebrity supporters include Sir Elton John and Sinitta.
