The lovebirds, who first met while competing together on season 25 of Dancing With the Stars, announced via social media on Friday that they're engaged. According to their posts, Artem popped the question to Nikki back in November, while the two were vacationing in France with their families.
"You are the best thing that has ever happened to me," the 37-year-old dancer tweeted, alongside a photo of Nikki showing off her stunning engagement ring. "So excited for what’s to come. I love you more than anything and thank you for saying 'Yes.'"

Fellow DWTS pro Sharna Burgess was one of the first to congratulate the couple, along with current mirrorball champion Alan Bersten. "Love love love this," Sharna wrote. "Congratulations you guys ♥️♥️♥️♥️♥️♥️."
"What!!!!!!" Alan added. "Congrats!!!!!!"
Celebrity engagement ring expert Kathryn Money of Brilliant Earth tells ET that Nikki's glamorous ring features an estimated 2-2.5 carat emerald cut diamond accented with tapered baguette diamonds and set on a white gold or platinum band. The elegant simplicity of the ring's design allows the gorgeous, show stopping center diamond to be the focal point. Depending on the quality and specific characteristics of the center gemstone, she estimates the cost of the ring to be between $20,000-$40,000.
ET has also learned that Nikki and Artem's engagement will be covered in the next season of Total Bellas, premiering this spring.
"Our first date was at the farmer's market in Studio City, and I had no idea that it was filled with paparazzi," Nikki recalled. "So Artem and I are, like, looking at vegetables -- and I honestly think he was picking up tomatoes -- and I see a paparazzi in this corner, and one in the other corner and I just freaked. I walked away from him, all the way to my car that was parked at Von's and I drove off. And poor Artem, all of a sudden I get a text like, 'Uhh, where did you go?' I didn't even say anything."
Flash forward to a year later, however, Nikki couldn't imagine her life without Artem. "I feel like Artem balances me in all the right ways. I get so busy and get into hustler mode so much and Artem just literally, and this is such a weird analogy, but he does make me stop and smell the roses," she gushed. "He makes me enjoy life in such a simple way and I love it."
And the feeling is mutual for Artem.
"I think Nicole came into my life at the right time. She's been nothing but supportive, and is the most positive person," he told ET in August. "I left my family when I was 15 and I never had a person next to me that kind of had an interest in me to succeed and be better. I think she's the first person that's given me that feeling."
