“The Voice” gave a sneak-peek of Justin Bieber’s new “Boyfriend” video with special guest, none other than Justin Bieber himself.

After the video, Justin went to greet the judges – Adam Levine, Cee-Lo Green, Christina Aguilera and Blake Shelton but something funny happened. Christina Aguilera extended her hand to shake with Justin but Justin came in for the kiss.

Check out Christina’s face afterwards, looks kind of stank…
