celebrated her 31st birthday on Friday, and to commemorate the special occasion, the Dancing With the Stars pro shared a heartwarming snapshot of her insanely cute son, Shai.

The gorgeous new mom -- who tied the knot with her longtime love, DWTS co-star Maks Chmerkovskiy, on July 8 -- took to Instagram to post a photo from the ceremony of her and her husband's 7-month-old son, dressed to the nines in a fancy white ensemble for the special occasion.

"M Y L I G H T, my eternal love. Shai Aleksander Chmerkovskiy, on my birthday there is nothing more that I want than to be with you," Murgatroyd captioned the sweet photo, in which she looks radiant in her lavish wedding gown while holding a smiling Shai in her arms.

This is the first photo the couple have shared of their handsome son from their gorgeous wedding, but it's clear that Shai fit right in at his parent's stunning ceremony at Oheka Castle in Long Island, New York.
