As if the excitement of the US Voice final wasn't enough, borewizards Lady Antebellum and Hall & Oates will be around to shove proceedings firmly over the edge.
Daryl and John will sing 1976's 'Rich Girl', reports Huffington Post.
Justin Bieber will be performing 'Boyfriend' as he previously announced, and Flo Rida (sans Sia) will give a rendition of 'Wild Ones' in a two-song 'medley' to help reign things in a bit.
The finale will take place across two shows on Tuesday May 8 and Wednesday May 9.
