"Our MADDOX is like the beginning of all things – wonder, hope, and a dream of possibilities. My life and our families [sic] home is changed forever," the proud mama, 28, captioned a photo of her little boy's hand. "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."

She continued, "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."

The first-time dad, 33, also posted a black-and-white image of his son holding his finger, taking the opportunity to gush about his dancer wife.

"'She can make angels, I've seen it with my own eyes….' Allison you never cease to amaze me," the Magic Mike XXL star wrote. "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."

The couple tied the knot in 2013 after meeting on the all-star season of the reality dancing competition in 2010, and announced their pregnancy in December. Allison is already mom to seven-year-old daughter Weslie from a previous relationship.

Congrats to the happy family!
