Nick Jonas thinks his wife Priyanka Chopra Jonas deserves "all the happiness in the world"

Alongside some photos of the Hollywood star, Nick wrote: "Happy birthday my love. You deserve all the happiness in the world. Today and every day. I love you. (sic)"

Priyanka - who married Nick in 2018 - has also posted a behind-the-scenes photo of her birthday celebrations on her own Instagram Story.

The 'Baywatch' star posted a photo of a bottle of wine and some confetti on a table, as she celebrated the occasion.

Nick previously explained that he has a "magical connection" with the actress.

Asked how their romance differs from his earlier relationships, he said:

"It's just that magical connection you've got with somebody when it's right."

Nick also revealed that they developed a strong friendship before they started dating.

He explained: "We're very lucky. We knew each other well before we started dating properly, and I think that foundation as friends always helps in relationships that have evolved in an organic way.

"It's been a wild first couple of years of marriage, and I'm very blessed to have a life partner that I can rely on, and vice versa hopefully."

Priyanka has also proven to be a source of inspiration for her husband.

Speaking about how Priyanka inspires his music, Nick shared: "Most of the songs are pretty much just love letters, which, when I can't articulate the way I feel with my words with no music, I go to the studio.

"And I'm grateful to have that because it makes her happy, and that's most important."
