Allison Holker and Stephen "tWitch" Boss have revealed the first adorable photos of their newborn son Maddox Laurel Boss.

On Tuesday, Holker shared an image of Maddox on Instagram as he was sleeping under a white blanket. Alongside the picture, the pro dancer made vows to her son and explained how she'll be a permanent presence in his life.

"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," Holker captioned the photo.

"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 boutonniere. 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."

Boss posted a different photo of the family of three on his own Instagram account.

"On Easter Sunday, my family was blessed with a once in a lifetime event. Our baby boy, Maddox Laurel, made his entrance into the world surrounded by laughter, love, and light. I'm amazed every moment by how much his arrival has enriched and deepened the love in the Boss tribe," Boss wrote.

"Maddox we are so proud of everything you are doing from opening your eyes, holding your head up, regularly pissing and pooping (only a parent can love that), and those little moments you smile back at us as we are smiling at you. This world is yours for the taking and equipped with your mother's beauty, wit, charm, brains, tenacity, and pretty much every good quality----combined with my ability to make sure you don't get TOO CRAZY and act like a GENTLEMAN---your life is gonna be amazing with whatever you choose to do with it."

He continued, "We will always have your back because at the end of the day, you are a BOSS! We love you son. From your dedicated and at times will be annoying but always loving -Dad #BabyBoss #MaddoxLaurel #BossBoy #HeWillBeLikeAMiniMe #MatchingOutfitsAndAll #RaisingAGentlemanALoverAFriend #MaybeItsTooEarlyToCallHimALover #ThoughHeIsCharming #LTTLlp."

Holker first announced her pregnancy during an October broadcast of Dancing with the Stars' 21st season. She welcomed Boss and her seven-year-old daughter from a previous relationship backstage when revealing the big news. The couple then confirmed the sex of their baby in early December.

Married by SYTYCD co-executive producer Jeff Thacker, Holker and Boss exchanged vows at SYTYCD creator and judge Nigel Lythgoe's California vineyard and winery in December 2013.

Holker joined Dancing with the Stars as a pro for Season 19. She was also a Top 8 finalist on the second season of So You Think You Can Dance.

Boss finished as the runner-up of SYTYCD's fourth edition. A romance sparked in 2010 when he and Holker both starred on the seventh season of the series as all-star partners for the contestants. Boss also just served as team captain of the "Street" dancers on last summer's edition of SYTYCD.
