Kirstie is already such a wonderful mom

Omgggg Uncle Mitchy just absolutely GUSHINGGGG over Evie is exactly what I needed today😍😌 but I really need Kevin's reaction now😂

Elliana: 😐 Kirstin: "Do do do do-do~ 😚"

Aww Kirstie, she is absolutely perfect! I'm so happy to see that she'll have such doting honorary uncles. And Mitch, he's completely in love. The way he gushes over her is adorable!

Elliana is so cute! The guys' reactions are adorable. Mitch is right, she is a princess along with Kaia. They are going to be so spoiled by their uncles, in the best way of course.

They're a big family together from a long time. I'm glad to see this. Wish the best to them 😊🎉

I love how they really are one big family❣️

0:13 “which one’s kirstie and which one’s ellianna?” GOT ME THERE 😂

OMG the rolls!! She’s so precious!!

I love the same reaction from each of them. It's the deep breath in, the huge smile and the waves of affection. Its lovely to see a new person be so loved by so many.

So adorable! Both Kirstin and Elliana!! And all her Uncles!!!

I love how happy everyone is to see her and how sweetly they all greet her:)

This was pure Serotonin

OMG, so much cuteness, I am crying 🥰💖😍. I just looove Mitch's reaction 😍🥰

Omg look at all those chunky baby rolls. My ovaries are screaming 😱 😍😍😍She is adorable!!!

The new member is absolutely adorable. I love this video. It brightened up my whole day. She's so cute.

She is so cute! I can’t believe she is tolerating that wig so well, my kids wouldn’t even wear hats at that age. 😊

I don't know how well that baby is going to sing, but it's nice to see a professional group giving a newbie a chance.

What a gift it is to have such a family in your place of work, I love love LOVE the bond between the Pentatonix members! Also, it’s so incredible how the trio have grown up together and now they’re celebrated artists who get to bring the other important people in their lives with them and still get to do it all together, absolutely amazing ❤️❤️❤️❤️❤️

Oh myyyyy!!! That gorgeous lil girl has 4 extra honorary dads, uncles and protection detail. They just melt - and it is so sweet to watch.

How to turn Matt into an alto in one simple step!! LMBO!! Also, I agree that she is the cutest baby that I have ever seen-ah. ;)

She is soooooo adorable 🥰🥰🥰

The perfect addition to the group! She will be just as beautiful as her mom. I hope she will sing as well as her mommy!

Those sweet baby rolls are everything. She's so squishy and gorgeous and content with her momma. ❤️❤️❤️
