Luckily, one fan was able to get a hold of the video and posted it on Twitter. In the short clip, Moore was simply talking about karma.

"Lots of birdies chirping out there. I hear it, I see it, I'm sure a lot of you do to so I'm just gonna say this. I believe in karma. Good things happen to good people, honest people, hardworking people, people who believe in basic goodness, people who believe in themselves, people who believe in others... Good things will happen to you. It's not always easy, but you gotta grind it out and you gonna believe in you. Treat people how you expect them to treat you. Celebrate yourself; celebrate your blessings as you should. But just know that you're not better than anybody. We all have our own gifts... Appreciate other people's gifts," he said.

Meanwhile, IBTimes reported that Moore and Gibson had a tense relationship on the set of "Criminal Minds." This is why fans of the series speculated that the former was throwing shade in the latter in the clip. It was also revealed that Moore was almost always late on the set of "Criminal Minds" and this worsened their relationship with each other.

In other news, Gibson was involved in an altercation on the set of "Criminal Minds." At that time, Gibson was directing an episode when he had a disagreement with one of the other staff. Their creative differences resulted in Gibson kicking the staff. Immediately after, the staff complained to the HR department, and Gibson was suspended for two days. The network later on decided to fire the actor.

As of late, it is still unclear who will take Gibson's place in the series or if his character Hotch will be killed off.

"Criminal Minds" season 12 will premiere on NBC on Sept. 28 at 9 p.m. ET.
