It’s official: All of the Jonas brothers have met their little niece! Kevin and his wife Danielle welcomed daughter Alena Rose this Sunday, and middle brother Joe Jonas rushed over to meet her as soon as they got home from the hospital.

Youngest brother Nick was off doing media interviews, but hopped a plane back to L.A. as soon as he could. During an interview for Demi Lovato’s upcoming Neon Lights tour, for which he’s serving as creative director, Nick told E! News, "I'm actually flying right after this to meet my niece for the first time.”

By February 6, Nick was holding the precious newborn in his arms, and he quickly posted an Instagram photo for all to see. In the photo, Nick is seen wearing a newsboy cap and dark jacket as he holds little Alena in his arms.

The infant is wrapped in a pink blanket, and she’s wearing a pink outfit covered in hearts. Her eyes are open, big and wide, and it’s probably the best close-up look at her face we’ve seen so far. “My beautiful niece Alena Rose,” Nick wrote.

Nick’s clearly smitten, but no one seems more excited than new dad Kevin. Nick told E! that his old bro is so "in love” with his newborn daughter. ”It's ridiculous. He sends me pictures every 10 minutes. I think it's just like the joy of his life right now." Congrats to the whole Jonas clan on their beautiful new addition!
