It's hard to believe it's been a year since the tragic [article id="1679049"]death of Whitney Houston[/article]
 on the eve of the 2012 Grammy Awards.

Grammy producers scrambled in the 24 hours before the broadcast to pay tribute to the "I Will Always Love You" star, coming up with a show-stopping number from Jennifer Hudson that set off a year-long series of all-star celebrations of Whitney's life and music.

Before Monday's one-year anniversary of Houston's passing, MTV News looks back at the artists and shows that have paid tribute to Houston.

 just hours after news of Houston's death[/article] on the night before the big show was like no other. Davis delivered a moving eulogy for his close friend and greatest discovery, telling the star-studded crowd, "I don't have to mask my emotions, not in front of this room filled with so many dear friends. I am personally devastated. Whitney was so full of life ... she was a beautiful person with talent beyond compare. She graced the stage with a regal presence ... and her family asked that the show go on."

Then everyone from Britney Spears to Serena Williams, Adam Lambert and Diddy joined him in a moment of silence, followed by performances from Ne-Yo and Pitbull, Alicia Keys, Wiz Khalifa and Jessie J, all of whom celebrated Whitney's influence and legacy.

 Brandy, Jordin Sparks, Ledisi and Melanie Fiona took on such titanic hits as "I'm Every Woman," "I Wanna Dance With Somebody," "It's Not Right, But It's Okay" and "How Will I Know." Brandy kicked things off by recalling her first memories of the legendary singer. "The first concert I ever went to was a Whitney Houston show and I was determined to get close to her," she told the crowd. "I talked my way through security until I finally made it backstage, but by then she was already gone. Years later, I finally got to meet her and even shared the 'VH1 Divas' stage with her."

A Death in the Family

Among those giving their personal accounts are: Clive Davis, Dave Grohl, Jennifer Hudson, host LL Cool J, Bruno Mars, Katy Perry, Bruce Springsteen and Taylor Swift.
