The Grammys rode the 3D wave today with a special effects laden tribute to the late Michael Jackson.Carrie Underwood, Celine Dion, Jennifer Hudson, Smokey Robinson and Usher performed in the tribute, mingling their voices with the voice of the late King of Pop against the backdrop of a 3D film featuring Jackson's 1995 eco-friendly Earth Song.
Free 3D glasses were distributed across the US so viewers could watch the show in 3D from their living rooms.
The Grammys' 3D effort follows the huge success of James Cameron's Avatar, which recently became the highest-grossing movie worldwide.
Jackson's children - Prince Michael, 12, and Paris, 11 - appeared after the tribute to accept a lifetime achievement award for the singer, who died in June of a prescription drug overdose.
"We are proud to accept this award on behalf of our father," Prince said.
There were plenty of other spectacular moments during the Grammys telecast, which opened with the flamboyant Lady Gaga performing her hit Poker Face in a glittery green butterfly outfit, falling prey to a faux kidnapping onstage and then materialising to perform opposite Elton John.
Multiple Grammy winner Beyonce belted out If I Were A Boy while Pink sang Glitter In The Air scantily clad and suspended from the air on a rope above the audience.
