The heartwarming image saw Artem dote on his new bundle of joy, who lay in his arms fast asleep. Nikki and Artem first met when they were partnered up on Dancing with the Stars in 2017. They got engaged in Paris in November 2019, two and a half weeks before they found out Nikki was pregnant with their first child.
Meanwhile, the past few weeks have no doubt been emotional for the new dad - not only has he welcomed his first child but the 38-year-old is now preparing for his return to Dancing with the Stars after missing out on last year's series.

Last week, Artem appeared on Good Morning America to speak about his baby son whilst confirming his return to the dance show. "I just can't wait to get back… I want to dedicate this season to my little boy," he said.
Of fatherhood, Artem explained: "It has been the most incredible feeling I just didn't know that I would have so much love to give. It's just incredible."
However, Artem confessed that his baby son "literally owns us". He added: "He's been waking up every hour and a half and I really feel bad for Nikki because he's a really good eater, so he's been on it."
