A ton of people wished the happy couple congratulations...
...including Joe's brother Nick, who had one of the sweetest messages of them all.
Well, it looks as if Nick is back at it with his magic words because — in a recent interview with Entertainment Tonight — he gushed about his big bro and future sister-in-law:
He said, "I can tell you that [Joe] found his partner and love of his life. That's all that matters. It's a beautiful thing."
He also revealed that Sophie wouldn't suffer any "new family member hazing" since she "already had her first sort of Jonas experience" last Thanksgiving.
