Brad Pitt Once Again Supports Late Friend Chris Cornell's Two Kids at Starry Tribute Show

Brad Pitt is still showing up for his late friend Chris Cornell.

The 55-year-old actor made an appearance at The Forum in Los Angeles on Wednesday for a tribute concert to the late Audioslave and Soundgarden frontman. The rocker died by suicide at age 52 in May 2017.

The five-hour show, titled I Am The Highway, featured several performances by Soundgarden, Metallica, Ryan Adams and the Foo Fighters. Other big names like Jimmy Kimmel and Josh Brolin joined Pitt in introducing the acts. Fiona Apple, Miguel, Adam Levine and Miley Cyrus were among the other artists to hit the stage.

Pitt also posed backstage with two of Cornell’s kids: daughter Toni, 14, and son Christopher, 13. Cornell is also survived by 18-year-old daughter Lillian.

The trio wore all black as they smiled softly for the camera and Toni leaned into her late dad’s close friend.

This isn’t the first time Pitt has been there for his late friend’s young kids. Just a month after Cornell’s death, Pitt was seen taking Toni and Chris to Universal Studios for a fun-packed theme park day. The rocker had been laid to rest just a few days before the outing.

“Brad loved Chris and of course will be there for his family,” a source told PEOPLE at the time.

Fans posted sightings of Pitt and the kids on social media throughout the day. They were spotted walking around Simpsons Land, sipping butterbeer from The Wizarding World of Harry Potter and riding the Jurassic Park-themed water coaster.

While Cornell’s death was ruled a suicide, his family has stated that they didn’t believe Cornell to be suicidal. The star’s wife Vicky said she believes that the side effects of the prescription drug Ativan — which can cause worsening depression and thoughts of self-harm in rare cases — may have impacted Cornell.
