The 36-year-old professional dancer and "Dancing with the Stars" alum confirmed the birth of her second child, son Kaspyan, with boyfriend Nevin Millan in an Instagram post Tuesday.
"@nevinmillan & I would like to announce the birth of our baby boy, Kaspyan Millan, over the Labor Day weekend," Trebunskaya wrote. "It was a beautiful, natural water birth at home. Mama, baby and family are doing great!"
"Thank you for all the love and support!" she added to her followers.
Us Weekly reported Kaspyan was born Saturday, Sept. 2.
Trebunskaya told the magazine her son is "beautiful" and "healthy," adding she "couldn't have asked for a more perfect birth experience."
"We are all so excited to get to know the new addition to our family and so grateful and blessed for this lovely gift!" the star gushed.
Trebunskaya already shares 3-year-old daughter Amalya with Millan. She previously told Us Weekly her family was looking forward to welcoming a baby boy into the mix.
"The most excited is my daughter. She keeps saying, 'It's too long mom,' nine months -- that's a third of her life!" the dancer said.
"Nevin is excited to have another man, another little guy in the house. He can't wait to take him to sporting events and sport games and all of that boy stuff," she added. "We're all so thrilled."
