ET has reached out to both her and Chmerkovskiy's reps.
The DWTS pros got engaged last December, when 36-year-old Chmerkovskiy proposed onstage at the Sway: A Dance Trilogy show in Miami.
"I couldn't see myself with anybody else," Murgatroyd told ET exclusively in December of her fiance at the Children's Miracle Network Winter Wonderland Ball in Hollywood, California. "He's the love of my life."
And Murgatroyd has plenty to celebrate these days. The dancer and her DWTS partner this season, deaf model Nyle DiMarco, won the coveted Mirror Ball trophy on Tuesday night, beating out UFC star Paige VanZant and Good Morning America meteorologist Ginger Zee.
"The first week that we worked together, she was already starting to learn my language and my culture. She was very curious," DiMarco explained. "She did the right thing right out of the chute. It really was about learning about each other's worlds and I think that message was really strong."
"Thank you all for your CONTINUING SUPPORT. @petamurgatroyd YOU ARE AMAZING," DiMarco also gushed about his partner on Instagram. "Thank you for embracing this journey with me. Thank you for pushing me and believing in me. I love you!"
