Robert Trujillo will be going gaga at the Grammys…

The 52-year-old Mexican American musician and his Metallica bandmates, previously announced performers at this year’s Grammy Awards, will be taking the stage with Lady Gaga.

Fresh off her acclaimed Super Bowl LI halftime show, Lady Gaga will mash up with Metallica for a very special one-time hook-up on the show airing Sunday.

Metallica was recently forced to postpone a show in Copenhagen due to vocal issues affecting singer James Hetfield. But back on January 14, the metal icons teased “something very unique and special” in store when they announced they would be hitting the Grammy stage again.

“It’s been three years since we were lucky enough to participate in the awards show when we last performed with world-renowned Chinese concert pianist Lang Lang and we’re thrilled to be asked back,” the wrote. “We have something very unique and special planned for this celebratory night, so tune in to watch on CBS-TV.”

The Grammy Awards will take place on February 12 at the Staples Center in Los Angeles with host James Corden. It will be broadcast live at 8 :00 pm EST on CBS.

Following the show, Trujillo and his bandmates will rush over from their performance at Staples Center in downtown L.A. to Hollywood to perform as part of “Citi Sound Vault,” Citi‘s new live music initiative in conjunction with Live Nation.
