Ummm ... can we put this on the list of things you should absolutely NEVER say on live TV?

While receiving his Teen Choice Award for Social Media King on Sunday (July 31), Vine star Cameron Dallas was giddy and excited. This may be why his brain to mouth filter wasn't exactly on his side.

Playing a quick game of "Would You Rather" backstage, Dallas was asked whose toothbrush he would rather use, Justin Timberlake or Jessica Alba. He chose Justin Timberlake ... which would have been fine if he left it at that. But, he didn't. Dallas followed up his comment by slut-shaming Jessica Alba.

"I would honestly choose Justin Timberlake just because I don't know where Jessica's been," Dallas laughingly says.

For being king of all social media, Twitter sure was quick to turn on the Vine star for his off-color comment.

Jessica Alba chose to rise above and ignored the comment in favor of speaking out against gun violence in a moving tribute later on in the show.

Rather than apologize Cameron Dallas reaffirmed to his 8.22 million followers on Twitter that the glib insult was a joke and he'd be happy to share a toothbrush with Alba. He then urged everyone to focus on the issues that really matter.
