Jessie J can be seen getting emotional in a new Comic Relief clip that highlights why the singer is teaming up with the charity this year.

The 'Domino' star is due to shave her head live on TV during Friday's (March 15) Red Nose Day in an effort to raise funds for the good cause.

Comic Relief helps those in need across Africa and UK and a new video has shown Jessie J visiting people in England that will benefit from the charity money.

The Voice UK coach meets a HIV support group as well as a foundation that helps those who have been involved in sex-trafficking.

It gets too much for the talented singer, however, who is unable to control her emotions whilst speaking to the camera.
