Over the weekend, Cheryl saw her last two remaining acts - 4th Impact and Reggie 'N' Bollie - make it through to the next round.
With both acts having already secured a place on the live tour next year, they are now in the final five of the competition.
Cheryl also made headlines this weekend after The Apprentice star Lord Alan Sugar publicly slammed the former Girls Aloud star as he watched the ITV talent show.
