An all-out dance party is in order: Allison Holker and Stephen “tWitch” Boss have welcomed their son!

Holker, who met her husband while they were both competing on So You Think You Can Dance, gave birth to their baby boy on Sunday, March 27, their rep confirms to PEOPLE.

Born in Los Angeles, son Maddox Laurel Boss weighed in at 8 lbs., 15 oz., and measured 22 inches.

“[Maddox’s birth] was truly an unforgettable moment and we are grateful to everyone that shared in the experience and made it so monumental. Our family feels full!” the proud new parents say in a statement.

And big sister Weslie, 7, is already head over heels for the new addition.

“Maddox already has the best big sister Weslie, they have already bonded and share a truly beautiful love,” the couple add.

Sharing a photo of her newborn son’s hand gripping her own on Instagram, Holker writes, “Our MADDOX is like the beginning of all things — wonder, hope, and a dream of possibilities. My life and our families home is changed forever. He blessed our lives exactly a week ago and it will never be the same again, and he has brought such a beautiful joy with him. We will let every moment sink in and last a lifetime! This is our family, our happiness and our future. WE WILL LOVE YOU FOREVER MADDOX LAUREL BOSS.”

tWitch shared his own special message on Instagram, giving a shoutout to his wife for delivering their son.

“‘She can make angels, I’ve seen it with my own eyes….’ Allison you never cease to amaze me. I love you and thank you for bringing in our little angel in so gracefully. Seriously, I fall in love with you over and over again because you are such a champion,” he writes.

Debuting their son on Instagram in an image by Jessica Janae Photography, Holker wrote, “He has already stolen my heart with his big bright eyes, stunning radiant smile and the way he snuggles perfectly into my arms, he is perfect in every way! He is and will always be my precious boy. And I feel so blessed to be his mother.”

On Easter Sunday I gave birth to our Son MADDOX LAUREL BOSS he was 8 lbs 15 oz and full of joy. He has already stolen my heart with is big bright eyes, stunning radiant smile and the way he snuggles perfectly into my arms, he is perfect in every way! He is and will always be my precious boy. And I feel so blessed to be his mother. To Maddox: I promise to love you forever, i will lead, I will teach, i will be strong, I will listen, I will be an example. I will be a shoulder to cry on when u need it, I will have a bandaid ready for when u fall, i will walk you into your first day of school and help u study for ur first test , I won't help teach u to drive ( leave that to dad, the one that is a good driver) but I will help u pin on ur first prom boutonnière. I will be there for it all and you every step of the way . I AM your mother and that is unconditional and everlasting! I LOVE YOU MADDOX and welcome to our family.

The couple revealed that they were expecting on an October episode of Dancing with the Stars and, soon after, shared that they would be having a baby boy.

They prepared for the birth of their son with a funky, non-traditional baby shower in February.

“It has been so hard to keep it bottled up inside me — both literally and figuratively!” Holker, 28, told PEOPLE after announcing her pregnancy to the world.

“I’m so excited for everyone to know and be able to celebrate with us because our whole family is just so excited about this. It’s the biggest blessing.”

Holker didn’t let her pregnancy keep her off the dance floor. She spoke to Fit Pregnancy and Baby in its March issue about being the first woman in DWTS history to compete while pregnant.

“There I was in these itty-bitty costumes, flaunting myself, at four-and-a-half months pregnant,” she said, adding that, “If you’ve ever been pregnant, you know that even in those first few weeks, you have to make frequent trips to the restroom. Well, I had to go what felt like 20 times during a show, and I needed three people to help me peel the outfit on and off each time. I couldn’t do it myself!”

She also spoke to the magazine about being excited to go into labor.

“Who knows? It could turn into a dance party,” she joked. “There may be twerking!”

Aww, I love these two! I love that they met on SYTYCD. It’s such a fantastic show and it’s great to hear the success stories of people who have competed on it. I was able to see the Season 5 dancers during their tour and it was by far one of the best live shows I’ve ever seen.

What a beautiful baby! Did he just come up with those words about her creating angels or is that from a poem or something? Because that’s one of the most beautiful things I have ever heard. She is one lucky woman.

Awesome flash mob! I love this video, what a great idea, what a beautiful couple. And that is one gorgeous baby, wow. They all looks so happy, it’s nice to see. Makes me happy.

I’m just gonna say it….. That baby is adorable but does not look black at all. He doesn’t even look biracial in these pics (maybe in person).
