Anna Trebunskaya is going to be a mother of two. The 36-year-old "Dancing with the Stars" professional dancer announced in an Instagram post Wednesday that she's pregnant and expecting her second child with boyfriend Nevin Millan. "Well, it looks like @nevinmillan and I will be welcoming another #tinydancer or #littleartist into our family! Amalya is going to be a big sister!" she captioned a photo of herself with her beau. Trebunskaya and Millan are already parents to 4-year-old daughter Amalya. The dancer couldn't help but gush about motherhood and Millan's active role as a parent in an interview with People after Amalya's birth. "I'm feeling good," she told the magazine. [Motherhood is] nice. It's very different than the kind of life I had before. This is different. This is great." "He's a hands-on dad and does everything I do except breastfeed," the star added of Millan. "We both were ready for this step. We're not 18, you know! Having kids is something we both wanted. We adore each other so we're excited to be on this journey together." Trebunskaya competed as a pro on 11 seasons of "Dancing with the Stars," and was last partnered with actor Gary Busey in Season 21. She previously voiced interest in returning to the show after Amalya's birth. "I'm looking forward to getting back into shape and dancing afterward and bringing the baby on board into the DWTS family!" the dancer told Us Weekly in 2013.
