Nick Jonas and Priyanka Chopra talk their couple name

If you haven't already been very charmed by Nick Jonas and Priyanka Chopra's courtship — the double dates! the social media PDA! the dancing! — firstly, how is that even possible? And secondly, prepare to be converted to Team Priyanka and Nick.

During an appearance on The Tonight Show Starring Jimmy Fallon on Friday night, Nick opened up about their engagement.

"We did this beautiful Roka ceremony," he said. "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 and get to know each other.

"It's really incredible. 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."

But more importantly, when asked if they have a celebrity couple name, Priyanka chimed in —from the side of the stage — yelling: "Prick!"

And Nick confirmed: "She likes Prick," but then added, "I don't like that one that much."

The couple confirmed their engagement last month after a lot of speculation on social media. Jonas and Chopra like to keep their relationship low-key, with the latter saying her "personal life is not for public consumption".

She said: "Ninety per cent of my life is for public consumption, but 10 per cent is for me. I'm a girl; I have the right to keep that to myself.
