Preparing for baby number two!

In February of 2014, the couple welcomed their first child into the world, a girl named Alena Rose Jonas.

At the time of their second pregnancy, a rep released the following statement:

We are excited to share the news that we are expecting a new addition to our family this winter. Alena is beyond thrilled to be a big sister and we can't wait to meet the newest member of our family.

Nick Jonas has always loved his title of "uncle," and when he found out the news he was going to be an uncle to a new baby, he posted the following image of Alena on Instagram:

He wrote on the post,

I love his girl so much... So happy for my brother and sister in law. Can't wait to meet my next niece or nephew!

In fact, I'm going to say Nick Jonas is probably one of the coolest uncles a girl could have. Check out this post from her second birthday.

The doting uncle wrote,

My beautiful niece is 2 years old today. HAPPY BIRTHDAY ALENA! I love you and miss you very much. I can't wait to watch you grow up.

Now he has two nieces to spoil!
