"When I was 17, I visited Venice for the first time and thought it was the most romantic place in the world. I promised myself then that the next time I would come back to Venice was to propose to the woman I'd want to spend the rest of my life with," Chmerkovskiy shared. "Fifteen years later I kept my word. It was perfect."
"My life has changed because of [her,]" the former DWTS pro added of Johnson. "And I find myself to be the best version of myself that I've ever been. She's awesome."
The couple shared their happy news on social media Thursday, both posting a shot of a shocked Johnson accepting Chmerkovskiy's proposal.
"I knew the moment I met you, you were the man of my dreams and I wanted to be with you forever," Johnson wrote. "Babychka Мой любовь thank you for making my fairytale come true today! Cannot believe I get to call you my FIANCÉ!!!! #engaged."
Chmerkovskiy captioned his post, "I can't wait to make you my wife."
On Friday, the duo both shared a snap of Johnson smiling and holding out her left hand, displaying her new bling as she sat at a dinner table in front of a gorgeous sunset.
"He put a ring on it," Johnson wrote, while Chmerkovskiy simply captioned the image, "Fiancée."
While the couple likely hasn't even set a wedding date yet, if Chmerkovskiy had his way, kids could be in the cards sooner rather than later, telling PEOPLE in December that he has a bit of baby fever.
"Unfortunately, she doesn't," he added of Johnson with a laugh. "No she does, she does. I think she would love to be a mother, but she also has so many incredible things going on in her life and I would feel very selfish to interrupt them for nine months."
Johnson was recently promoted from the Dancing With the Stars troupe to full-on pro, partnering with Olympic figure skater Adam Rippon during the most recent, all-athletes season of the ABC competition show. The couple took home the Mirrorball Trophy as well, making it likely that Johnson will be sticking around the ballroom for a good while longer.
