Hollywood stars are throwing their support behind Alec Baldwin after a tragic on-set shooting that left one dead and another injured.

The 63-year-old actor was rehearsing a scene for his upcoming western-genre film "Rust" in New Mexico when he discharged a firearm that he was told was "cold" or unloaded, per affidavits. The projectile struck director of photography Halyna Hutchins and director Joel Souza.

Souza survived and has been released from the hospital while Hutchins died from her injuries.

Questions of who is to blame for the incident have floated since news broke, but Baldwin's fellow stars have spoken out in support of the actor as the investigation continues.

"Our hearts are broken along with yours," actor Leslie Jordan wrote. 

Model Brooks Nader added: "Sending so much love."

When Baldwin shared his own statement on social media, others offered him direct support as well.
