First, he probably has everything he could ever want, and second...he's kind of an old soul, despite just turning 21.
Nick had what we can only assume was an epic 21st birthday party in Las Vegas, with his brothers there, of course, as well as his new girlfriend, Olivia Culpo.
In a word, Olivia is gorgeous. In two words? Beyond gorgeous.
We love this pic of Nick and Olivia sharing a kiss at the big birthday bash--do we hear wedding bells?
It's maybe a little too early to tell, but they make one lovely couple, for sure.
On to the birthday gifts, though...
Nick's brother, Joe Jonas, tapped into his little brother's old spirit, as well as making the gift tie into their Vegas party quite nicely.
According to a report from the Las Vegas Sun, Joe gave Nick a pair of Frank Sinatra's tap shoes.
Olivia reportedly gave Nick a necklace--here's hoping he models it in another shirtless selfie.
We can only hope.
