Even as they celebrated their first ever Grammy nod, the Jonas Brothers still remembered what's most important. "Did anyone call Mom?" asked Kevin, not long after learning that he and his brothers had been nominated for best new artist.
Nick couldn't stop smiling after the band's nomination was announced Wednesday, says an onlooker. Meanwhile, Joe hugged everyone around him and Kevin leapt out of his seat.
Still, come Thursday morning, the brothers were back at work on the set of their upcoming TV show
, where the cast and crew toasted them with sparkling cider and showered them in confetti.
"It's a huge honor for us to be nominated," the brothers said in a message they later posted on their MySpace page. "As songwriters and musicians, we are truly grateful ... We thank every one, from our hearts, who voted for us. We are truly living our dream."
