"The 'Beautiful Child' video is for saving lives," Perrette told ET's Kevin Frazier. "It's to inform young kids out there (especially the LGBT kids, which are four times more likely to commit suicide) to let them know that there is a resource out there and that resource is The Trevor Project."

The Trevor Project is the leading national organization providing crisis intervention and suicide prevention services to lesbian, gay, bisexual, transgender and questioning young people.

The issue has touched Perrette's life in a personal way, and she revealed the specific instance that inspired her beautiful song.

"I had a friend of mine, who I go to church with, who happened to be a Trevor suicide hotline operator. Unfortunately, her younger brother committed suicide and it was so awful," Perrette shared. "As a songwriter, I did what I have to do to deal with those emotions and I wrote a song about it, then I called in this unbelievable group of people."

That group included Perrette's NCIS co-star Michael Weatherly and a few other surprise guests.

"[Weatherly] is a very talented musician," Perrette told ET. "He actually plays piano on every song that I've ever written that has piano in it. And then Kirsten Vangsness came down from Criminal Minds and sang on it. My darling Lance Bass sings on the thing."

According to Perrette, "Beautiful Child" is just a small taste of what's to come.

"I've got the record done," Perrette said. "I keep writing songs ... but we wanted to get this video out, you know, even before I get the whole record out."

"The whole point is to get more people and more people aware and to save lives," Perrette added.
