Let the countdown begin.
I caught up with National Academy of Recording Arts and Sciences (NARAS) president Neil Portnow last night to get the lowdown on Gaga's performance.
"She will take us through quite a bit of history of David Bowie's repertoire," Portnow said at the Academy and Clive Davis' Pre-Grammy Gala at the Beverly Hilton Hotel. "It's one of the longest, larger segments of the night."
He also added, "There's some very exciting brand new technology that's never been seen on television that will be a part of the segment."
Portnow said Gaga "popped into my head pretty quickly" when he first thought about including a Bowie tribute, but he wasn't sure she'd be up for it.
Fortunately, "she really wanted to do it and it worked out," he said.
Gaga has already celebrated the performance by getting a large tattoo of Bowie on the left side of her torso by celebrity tattoo artist Mark Mahoney on Saturday in West Hollywood.
