These boys couldn't be cuter.
On Tuesday, Dec. 15, Nikki Bella took to Instagram to share new adorable pictures of her son Matteo Chigvintsev and nephew Buddy Danielson. In the just-released images, Nikki's fiancé Artem Chigvintsev fed Matteo as a happy Buddy looked on.
In fact, Brie Bella and Daniel Bryan (born Bryan Danielson)'s son was full on beaming as his aunt Nikki held him. Meanwhile, Matteo was a total mood as he calmly worked through a bottle. What we would pay to achieve that level of peace!
And, don't get us started on Matteo's gorgeous head of hair. We can't believe how long the four-month-old's hair was in this pic. So gorgeous!
On the cousins' bonding time, Nikki wrote, "It's the most wonderful time of the year."
As E! readers may recall, the Total Bellas stars revealed their pregnancies in a joint announcement as they were due a week-and-a-half apart. Nikki and Artem welcomed little Matteo into the world on Jul. 31. Just one day later, Brie and Bryan's son Buddy arrived.
And, as the twins detailed in an October episode of The Bellas Podcast, the cute cousins have a special bond.
"Obviously, I do call them spiritual twins, but it's like they're legit siblings," Brie shared with listeners. "It's like they're used to each other."
Sounding off on this sentiment, Nikki dubbed Matteo and Buddy "half siblings."
Brie wrote in May 2021, "BFF's for Life."
"We all woke up late but just in time for the inauguration," Brie Bella wrote in January 2021. "First time I get to sit with my kids and explain it all to them!!! Bird said she wants Gaga's dresses!! Such a special day!!"
Brie revealed on Instagram, "Birdie telling Buddy all about sleeping on his own in his room. I can't believe the time has come!! My active rolling little boy is growing so fast!!!"
Nikki Bella captioned this tender photo of herself and Matteo Chigvintsev, "Mama + Teo vineyard walks."
Brie shared this picture of Buddy and grandma Kathy Colace Laurinaitis on Jan. 7.
Alongside this sweet pic of Matteo, Nikki stated, "My Sweet Potato King."
Nikki wrote, "Can't believe our baby boy is a few days over 23 weeks".
"Shared this with some friends," Nikki penned online. "Teo is becoming a lot like his Mama! Facials exact! lol"
Nikki shared on this Instagram snap, "My Russian Love & My Russian Bear".
"Ringing in the New Year with these Party Animals!!!" Brie wrote on Instagram. "Happy New Year's Bella Army."

At age 3, it is understandable that Brie Bella and Daniel Bryan's daughter Birdie Danielson would find Mega Bloks far more interesting than her baby brother Buddy Danielson.
Too cute!
