It looks like the friendship among the members of Fifth Harmony and Demi Lovato is based on jokes, some of them a little bit over the top.

Backstage of her Neon Nights Tour, the members of Fifth Harmony sought revenge of all the jokes Lovato has played on them. Dina Jane Hansen was in charge of the joke involving a huge cake, which ended on Lovato's face.

"I just want to say I love you" the singer said before smearing the cake all over the former Disney girl's face.

Among laughs, Lovato replied Dinah: "I'm going to kill you!, This is great!, and when I see you in L.A., your a** is mine".

With this love display, her friends Ally Brooke Hernandez, Normani Krodel, Dinah Jane Hansen, Camila Cabello and Lauren Jauregui showed their good relationship and how they enjoyed the tour.
