Sam has been given the honour of kicking off proceedings at the glittering ceremony and will be making her first live performance since winning the reality show in December.
NTA producers will be flying Michael in from Los Angeles for the special one-off performance. Joining Sam and Michael on stage will be the Thornhill Community Academy choir from Channel 4's Educating Yorkshire programme.
Viewers should expect Sam to show off her powerhouse vocals, as she'll be singing a rendition of Motown classic, 'Ain't No Mountain High Enough'.
Sam was crowned the winner of X Factor last month and went on to achieve a Christmas number one with her cover of Demi Lovato's hit single, 'Skyscraper'.
During the competition, Michael surprised Sam by visiting her during Big Band Week, where he gave out some valuable advice.
Sam was overjoyed after meeting her singing inspiration, and Michael also revealed how he was a huge fan of the rising star, saying he would work with her "in a heartbeat".
The NTAs, which honours televisions biggest stars, will be broadcast live on 22 January at 7.30pm on ITV.
