Justin Bieber Shocked, Then Stoked About Grammy Noms

Best New Artist nominee's My World 2.0 up for 2011 best pop award.

Though he was a bit tongue-tied when host LL Cool J asked him to react to his Grammy nomination for Best New Artist on Wednesday night during the "Grammy Nominations Concert Live!" special, Justin Bieber got his thoughts together a short time later and had a lot more to say about the honor.

"Just went to bed and thought I was nominated for 1 #grammy and was already freakin out ... then @scooterbraun [Bieber's manager] just called me ... 2 nominations!!," the 16-year-old star tweeted from London.

And as the news of his first-ever Grammy noms sunk in, Bieber couldn't contain his enthusiasm.

"What!?!? what?!?!!? 2!! #Heck yes!! Love everyone. Never say never!!!," he wrote, adding, "Win or lose ... this is #crazy!! the Grammys!!! #Holy crap!!!"

Those reactions were a bit more enthusiastic than the ones he gave on-air with host LL. During a brief back-and-forth on the show after Paramore's Hayley Williams announced the nominees for Best New Artist, Bieber seemed stunned and was at a loss for words when the rapper asked him how it felt.

"Wow. It feels amazing. I can't believe I'm in this position. I want to thank all my fans, everybody. I want to thank ... the board. I don't know what to say," Bieber stammered.

The teen idol has some pretty stiff competition in the new-artist category, including rapper Drake, buzz bands Florence & the Machine and Mumford & Sons and a dark-horse candidate, jazz singer Esperanza Spalding.

There aren't any slouches in the other category Bieber snagged a nomination in, either. His My World 2.0 will face off in the race for Best Pop Vocal Album against releases from Katy Perry, Lady Gaga, Susan Boyle and John Mayer.

Bieber performed his hit "Favorite Girl" on the Grammy concert special and later posted a video with a more-enthusiastic reaction to his double nomination.

"Hey everyone, it's 3 in the morning over here in London, and LL Cool J just told me I'm a Grammy-nominated artist," Bieber says in the clip, sitting calmly on a stool in a green-screen studio.

"I was a little nervous, shell-shocked. I didn't really get to show you guys how I really feel," he admits, before jumping out of his seat and shouting, "Yes! Yes! I am a Grammy-nominated artist! Never say never! Never say never!" as he spins in circles, pumps his fists and spikes his baseball hat on the ground.

The Best New Artist nod must have been especially sweet for JB, since just this January at the 2010 Grammy Awards, he and Ke$ha presented the statue in that category, and he said he was looking forward to possibly being on the stage again in 2011.
