In the photo, the celebrities are joined by their professional dance partners on the show's set. They're all holding their hands in the shape of a heart.
Among the posing cast members are Nikki Bella, Nick Lachey, Frankie Muniz, Sasha Pieterse and Drew Scott. The cast is also planning to observe a moment of silence during Monday night's episode in remembrance of the victims.
Scott shared the photo on his Instagram account with a caption meant to inspire the show's audience.
"We hope that dance will move you to inspire goodness in others, that the music will feed your soul, and that we can make you smile at a time that is so dark," Scott wrote. "Tonight we dance for you."
Scott, who has a home in Las Vegas, also shared an additional message about the shooting.
"My heart aches for all the families who lost loved ones in Vegas," he wrote. "How can there be so much hate in this world?"
Other cast members have also individually chimed in about the tragedy. Pieterse said her and her dance partner, Gleb Savchenko, won't spend the day promoting their DWTS appearance out of respect for the victims.0comments
