Bieber Fever reached an all-time high with Justin's scorching performance at the Grammys.
But the 16-year-old phenom's Grammy dreams came to a crushing end when he lost Best New Artist to Esperanza Spalding. It was a shocking upset, and instantly turned singer Esperanza Spalding into public enemy number one for scorned Bieber fanatics.
Esperanza's Wikipedia page was bombared with insults.
"Go die in a hole," someone wrote.
"No one even knows who this Esperanza chick is," went another nasty posting.
A disappointed Bieber took to Twitter after the loss, saying, "Was I upset? Yes. But I was happy for her also."
And there was no animosity when Bieber and Esperanza hugged it out backstage, meeting for the first time.
Bieber said to Esperanza, "I'm so happy for you."
Out on the red carpet, everyone was buzzing about Lady Gaga's 'egg'-celent entrance. The always outrageous star arrived inside a glowy egg, with a team of brawny guys hauling her on their shoulders like Cleopatra. There was even an oxygen tank inside the container to help the singer breathe.
Jersey Shore's The Situation told INSIDE EDITION on the red carpet, "Lady Gaga...last year she was meat, this year she's an egg. She just loves protein."
"I arrived in a French toast mobile. We're eventually going to form a meal," Kathy Griffin said.
Cyndi Lauper said, "Makes you think what came first, the chick, the egg?"
Gaga finally came out of her shell to perform her song Born This Way, wearing a yolk-colored ensemble.
She changed again into a hard black body mold to accept her award for Best Pop Album.
Miley Cyrus beamed on the red carpet, and Katy Perry had a very special date—her 90-year-old grandmother.
Inside, Perry revealed never-before-seen footage of her recent wedding to comedian Russell Brand. Nicole Kidman, clearly a Perry fan, sang along to her hit Teenage Dream.
It was a night of stellar performances. Rihanna rocked it, taking the stage twice. You would never know that the star was battling bronchitis.
"I'm on every med under the sun!" she tweeted on the way to the Grammys. "I don't wanna miss a thang!!!"
Christina Aguliera rebounded from her embarrassing Super Bowl performance, joining Jennifer Hudson and Martina McBride in a moving tribute to the Queen of Soul, Aretha Franklin.
Martina McBride told INSIDE EDITION, "She's an amazing singer. I stand right next to her and I get to hear her sing. I got to hear her sing several times everyday since Wednesday, and she's full-on blown me away every time."
Aguliera got all the words right, but had another slight stumble, almost falling at the end of her performance. Aguliera made light of the on-stage slip, saying to the audience, "That was a real sexy ending."
Aretha Franklin, reportedly still recovering from cancer surgery, didn't make it to the show, but appeared in a taped message, thanking everyone for her tribute.
Oscar®-winner Gwyneth Paltrow in a plunging black catsuit and sky-high heels was part of the Grammy's most colorful performance, singing "Forget You" with a feather-clad Cee Lo Green. Their back-up singers were none other than the Muppets!
After her performance, Gwyneth took in the rest of the show with good friend Beyonce.
Barbra Streisand made a rare performance and seemed relieved after her final note, saying, "I was so nervous!"
And legendary rocker Mick Jagger brought the house down, making his Grammy debut at 67 years old. That's right, 67! Mick got a rousing ovation from the star-studded crowd.
But the night belonged to Lady Antebellum. The country-pop group took home five Grammys, including Record of the Year.
And the indie rock band Arcade Fire won Album of the Year, capping off a string of major upsets on music's biggest night.
