Mariah Carey was Cleary Lip Syncing at the BET Awards Last night.  After allegations that Carey was lip syncing on May 16^th at the American Idol Finals, Mariah is back in the news for the BET Awards scandal.

Mariah Carey took to the stage at the Bet Awards to perform her new song "Beautiful" alongside singer Miguel and rapper Young Jeezy. But Mariah had clearly pre recorded her song and pretended to lip snc on stage.

Earlier this year, on the "Idol" finale, Carey was accused of not singing a medley of greatest hits live, which the singer's reps vehemently denied at the time. As of this writing, the reps had not returned a request for comment on her BET performance

This time around, flawless notes and perhaps un-flawless mouth movement is what appears to be fueling the media (and social media) speculation of Sunday night's awards show set.

So why is Mariah not using her famous singing voice? She's incredibly talented and there are very few artists out there that can hit the notes she's able to hit. But maybe her voice just isn't what it used to be like in the 90's.

The ironic part is what hisband Nick Cannon said about Mariah before the awads ceremony: 

"There's no management helping make decisions. Everything you see is all her, whether it's a collaboration when the lights hit, how she enters, she's doing all of that." Ha!

Twitters fans are mad at Mariah. One follower @Mariah Facini tweeted, " I don't even understand why Mariah Carey even came to the BET awards. She lip synced the entire time." Another @beachsax11 wrote, "Jeezy so shady. Talkin bout RIP to Mariah Carey vocals. Died in the 90s. All that lip synching. I'm so disappointed."

I agree. Either sing or don't go on stage. She's cheating her fans. What do you think?
