The DNCE singer decided it was time to make it permanent with his GoT bae, and Joe's family have already adopted Sophie as one of their own.
Nick just spoke with Entertainment Tonight about how excited the Jonas fam really is, and it's freaking adorable what he has to say about his brother's relationship.
"As someone that knows [Joe] very well, I can tell you that he found his partner and the love of his life," Nick said.
"That's all that matters. It's a beautiful thing.
CRYING.
Nick showed his excitement last month when the pair announced the engagement, writing on Twitter, "Ahh! Congratulations to my brother... and sister in law to be on your engagement. I love you both so much."
