The rockers - made up for Steven Tyler, 76, Tom Hamilton, 73, Brad Whitford, 72, Joe Perry, and Joey Kramer, both 74 - officially retired from touring last August after Steven suffered a fractured larynx, but they look set to return to the stage for the frontman's sixth annual Jam for Janie Grammy Awards Viewing Party.
Aerosmith are expected to reunite for a performance at the Hollywood Palladium-based charity event on February 2.
According to Billboard, Steven, Joe and Tom are expected to perform, but there isn't a mention of Brad and Joey, who last played with the group in 2019.
As well as supporting non-profit organisation Janie's Fund - which helps young women and girls who have suffered abuse - this year the spectacle will support the Los Angeles Fire Department Foundation and the Widows, Orphans, and Disabled Firefighter's Fund, amid the wildfires in California.
Steven said: "What the Los Angeles community has endured with these wildfires is unthinkable.
"Music has healing powers and we hope to bring a moment of joy and levity to our first-responder firefighters and those most affected by the fires.
"The trauma experienced by the girls we work with is also unthinkable and we will continue to shed light and support the amazing work of Janie's Fund."
Several other stars, including Alice Cooper, Dolly Parton, Jane Lynch, Lionel Richie, Melissa Joan Hart, Miley Cyrus, and Scarlett Johansson, are event chairs.
