Nick Jonas and Priyanka Chopra have a hilarious celebrity couple nickname!

American singer Nick Jonas has opened up about his engagement to actor Priyanka Chopra as he jokingly revealed that their celebrity nickname will be "Prick".

During an appearance on "The Tonight Show Starring Jimmy Fallon" on Friday, Jonas, 25, that he was quick to propose to Chopra as he knew she was the one right away.

Fallon asked whether they have thought of a nickname for themselves.

Priyanka, 36, who was standing at the side of the stage, yelled, "Prick".

"She likes Prick. I don't like that one that much," Jonas said as Fallon shot down the suggestion.

The singer said after they got engaged in America, they went to India for a traditional ceremony.

"After we got engaged, we went to India, to her home country, to Mumbai, and my parents came along. We did this beautiful Roka ceremony? It's a confirmation from both sides of the family that they approve of the engagement.

"There's some beautiful prayers and a connection just for the family to have a chance to meet and hang out. It's really incredible," Jonas said

He said they felt "full of joy" after their ceremony and thought that now they should make it public.

"We both left that ceremony so full of joy. For she and I, I think it was just nice to have that time with the family first. Have that private moment then be able to share with the world afterwards," Jonas said.
