Kid Rock Calls Out Billboard Music Awards Performers for Lip-Synching: [WATCH] 'Cowboy' Throws Shades, Drops Mic Before Presenting 'Best Rap Song' Award

Kid Rock wasn't nominated for a Billboard Music Award, nor did the "Cowboy" singer perform on Sunday night (May 19), but the "Best Rap Song" presenter still managed to steal the show with the line of the night:

"Let's give it up for people lip syncing to pre-recorded music."

This "shade" was thrown from the questionably intoxicated "Bawitdaba" singer who rocked shades, an army print vest, a top hat, and a coffee mug to the 2013 BBMA's at the MGM Grand Garden Arena in Las Vegas.

As if calling out some of the night's performers/"lip-syncers" for not actually singing during their performances wasn't hilarious enough, Kid Rock also dropped the microphone before the "Best Rap Song" nominees (Macklemore & Ryan Lewis, Flo Rida, Kanye West, and PSY) were announced.

Macklemore & Ryan Lewis ultimately took home the "Best Rap Song" award for their hit song "Thrift Shop" (for those who were too distracted by Kid Rock stumbling to read the card).

Kid Rock's apparent sarcastic comment was made within the first hour of the Billboard Awards ceremony, following Selena Gomez's "Come and Get It" performance and Chris Brown's rendition of "Fine China."

Although the "All Summer Long" singer may not have been completely sober when he made the lip-sync comment, Kid wasn't just kidding around. Many BBMA viewers agreed with the rocker and backed up Kid Rock for calling out the artists who appeared to be just mouthing the words to their songs and dancing, while the track played in the background.

Moments after Kid Rock took the stage and "threw shade" before presenting, Twitter posted their reactions to the apparent lip-lynching trend:

"Is this an award show or a competition of who can lip-sync the best? Can we get some talent up in here?! #BBMA #billboard"

"Why lip-sync if your WHOLE song is autotuned? Are you worried about sounding bad? #bbma"

"Kid Rock just called out the modern recording industry, then dropped the mic. Whether or not you like his music, respect! #billboard2013"

"BBMA's: The award show where everyone seems to lip-sync."

"Will.i.am  and Justin Bieber currently having a lip-sync off. #BBMA"

"Thank U for being real @KidRock !!!!! #lipsync call out! #BillboardAwards"

"Props to kid rock for having the balls to say what the rest of America is thinking I think the only 1s who weren't lip singing was bruno"

Here's the "Presenter of the Night" winner's clip if you happened to miss Kid's diss:

As for the lip-synching controversy, decide for yourself if artists like Selena Gomez & Chris Brown were actually singing during their 2013 Billboard performances....
