Ahead of Zlata's arrival, Gleb revealed via Instagram that he was taking a break from the DWTS: Live! Hot Summer Nights Tour to head to Australia.
"Hey guys, I just want to let you all know that I had the best time on the Hot Summer Nights Tour," he said in an "important announcement" video. "But I won't be doing shows anymore this tour because I'm going to join Elena in Sydney where our new baby girl is going to be born."
"Hope you all understand," he added. "And I'll see you real soon."
The dancing duo already has a 6-year-old daughter Olivia, and when the two stopped by ET's Los Angeles studio for Gleb's Facebook Live interview in May, they couldn't stop raving over what it's been like gearing up for baby No. 2.
"Again! Girl No. 2," Gleb exclaimed. "[Elena] is amazing, it's unbelievable. I feel like I'm the one who's like freaking out, stressing out, being, you know, overwhelmed, but she's… nothing, it's perfect. [It's] like she's not even pregnant. I only see the belly is growing."
"A summer baby," he added. "[Olivia's] super excited. She just said this morning, 'Mommy and Daddy, I'm going to choose who is going to be putting me to bed, who's going to put baby girl to bed, so you're going to be switching.' Daddy is going to be on the weekend, and you're going to be...' and I was like, 'OK!'"
