This Saturday night sees the new coach performing an off the cuff rendition of his hit Dance With Me Tonight during a break in filming of the Blind auditions.
Olly gets the audience singing along to his song, while standing on the show's famous red chairs.
And soon his fellow coaches will.i.am, Jennifer Hudson and Sir Tom Jones are also joining in as Olly takes to the stage.
After two weeks of blind auditions, Olly already as four acts on is team and is loving his time on the series.
He said: "It feels amazing. It is incredible to be part of such an amazing show and a show that I have watched from afar for many years.
"I am really enjoying being part of such a fun, exciting show, it is brilliant."
Olly, who rose to fame on The X Factor in 2009, reckons his talent show background will give him the edge.
He explained "It helps me to be able to give the contestants my advice and they also know I have been through that experience and I can help and guide them with that. If they have any questions they want to ask I can help them.
"But when they get to the later stages of the competition it is really about picking the right songs and that is what I want to try and get across to them. I hope they have the confidence in me to help them with that but they also need to know themselves and find themselves as an artist."
"I definitely think that the experiences I have had doing reality TV shows will definitely help them and that I have had such a successful career coming from a reality TV show, not many people get that opportunity so I am very lucky that I am part of that group," Olly added.
This Saturday evening sees Week 3 of series seven of The Voice UK which continues on its brand new home on ITV.
As always, the coaches will decide whether or not to spin based only on what they hear as they sit with their backs to the stage.
The Voice 2018 airs Saturday night at 8PM on ITV.
