[artist id="3187077"]Justin Bieber[/artist] was disappointed that he couldn't make it to Sunday's [article id="1642479"]2010 BET Awards[/article], where he was nominated for Best New Artist. He was on the road for his [article id="1642260"]just-launched My World headlining tour[/article], he explained on Twitter, and never considered cancelling or postponing the show.

"Rolled into Milwaukee for the show today...gonna be huge...22,000 people sold out. I heard. Missing everybody out in LA for the BET Awards," he tweeted on Sunday. "Just wanted to say I would have been at the awards, but this show was booked before the nominees came out, and I don't cancel shows.

"I would never cancel a show and let down the fans unless I had to ... but I do wish I was there too, because I am honored to just be nominated," he added. Though he lost the Best New Artist prize to Queens MC Nicki Minaj, the teen singer found the nomination enough of an honor. "But I do wish I was there too, because I am honored to just be nominated but just goes to show that music is COLOR BLIND!! It is the universal language, and good music brings us all together ... the way it should be."

Bieber added a message to his friends who were at the Shrine Auditorium. "Everyone out there best of luck... Shout-out to my big bro @usherraymondiv performing 2nite!"

And while the celebrities at the BET Awards were gathering trophies, Bieber celebrated another successful night of his tour in a less formal manner: with a water gun fight. "As soon as we got offstage we had an EPIC WATER FIGHT!!!" he wrote. "Last night we were caught off guard but 2nite we came prepared."
