Nick Jonas "just knew it was right" with Priyanka Chopra.
The 25-year-old singer couldn't believe how "immediately" he fell for the 'Baywatch' actress and they are "very happy" together.
He said: "Our lives were kind of taking us in different places. People thought we were being coy, and so did we until we cut to now [and] we're engaged. So, the story sort of wrote itself ... It was kind of immediate, and I think we just knew it was right and jumped right in. And we're very happy."
And the 'Jumanji: Welcome to the Jungle' star says it was "really special" throwing an engagement party in Priyanka's native Mumbai.
Speaking on The Tonight Show Starring Jimmy Fallon, he added: "It was really special. And, for she and I, I think it was just nice to be able to have that time with the family first and then be able to share with the world afterwards. And then we put it on Instagram and we're like, 'Oh my God. It's official.'"
Nick and Priyanka recently confirmed their engagement with sweet matching posts on Instagram.
Nick captioned the image: "Future Mrs. Jonas. My heart. My love ... Prayer, family and loved ones as the foundation to this new chapter (sic)"
Whilst Priyanka wrote: "Taken.. With all my heart and soul ... The only way to do this... with Family and God. Thank you all for your wishes and blessings (sic)"
Speculation mounted about an engagement after director Ali Abbas Zafar announced Priyanka was leaving the Indian film 'Bharat' and hinted that Nick had something to do with the decision.
He tweeted: "Yes Priyanka Chopra is no more part of @Bharat_TheFilm and the reason is very very special , she told us in the Nick of time about her decision and we are very happy for her ... Team Bharat wishes @priyankachopra loads of love & happiness for life (sic)."
