Alec Baldwin has a staunch supporter in his daughter Ireland.

The 63-year-old actor has been the subject of headlines for days since he discharged a firearm – he was told was cold or "unloaded" – on the set of his upcoming film "Rust," resulting in the death of cinematographer Halyna Hutchins.

An investigation has been opened into the New Mexico incident, though no charges have been filed yet. Director Joel Souza was also injured but has since been released from the hospital.

Not long after the shooting on Thursday, Ireland, 26, took to Instagram to share well wishes for Souza, Hutchins' loved ones and noting that she was "wishing I could hug my dad extra tight today."

On Wednesday, she continued to support her old man, taking to Instagram to praise a fan for sharing a positive memory of her father amid the ongoing investigation.

"Amongst some of the most abhorrent and threatening comments, emails, text messages, and voicemails I’ve been getting... this beautiful comment stands alone," the model wrote alongside a screenshot of a fan's supportive comment on a previous post.

In their comment re-shared by Ireland, the fan recalled working on the film "Thomas and the Magic Railroad," which saw Baldwin star as Mr. Conductor in a film about popular children's character Thomas the Tank Engine.

"I'd dealt with typing up some pretty goofy celebrity riders in my day but NOT your dads," they wrote. Riders are requests that a performer makes as criteria for performance.

"He only wanted to make sure he had milk and cereal in his hotel room for when his daughter was visiting," the commenter continued. "That was it. That was the whole rider. I'll always remember that."

The movie was filmed over the course of several months in 1999 just before Ireland turned four. At the time, Baldwin was married to Ireland's mother, Kim Basinger.
