Dance with the stars Map Murgatroyd expresses her grief over the death of the dancer and choreographer Serge Onik.

On Wednesday August 25, Peta took to Instagram to share a carousel of photos of the former So You Think You Can dance contestant, including several shots of the two together. Serge, who worked with Peta and her husband, Maksim Chmerkovskiy, in choreography for DWTS, was 33 years old, and his agent confirmed E! News on Tuesday, August 24th, although further details were not publicly disclosed.

“My Serge … my koala, I can’t believe it, I’m completely broken,” wrote Peta. “I am full of regret because I wanted to text you and tell you that I missed you last week and that it never crossed my mind. I hate how I forgot. I will always hate myself for it. My heart hurts, my eyes hurt and my soul burns to squeeze you one last time. I just need one last push and one last match fight like before. “
