But what REALLY turned heads was the sexy, cleavage-baring black dress Carey flaunted at the BET Honors on Saturday (Feb. 8).

Thankfully, the former "American Idol" diva didn't experience an embarrassing wardrobe malfunction, but she was close!

The 43-year-old beauty donned an original Rubin Singer with a VERY low-plunging neckline. She looked fantastic.

The BET event (held in Washington, DC) honored several big-name music legends including Aretha Franklin, Ice Cube, and Berry Gordy. Comedian Wayne Brady hosted, and some stand-out tributes included performances by Jennifer Hudson, Janelle Monae, and Smokey Robinson among others.

Carey gave a sultry, steamy performance of a brand-new, never-before-heard song. BET Honors will air to the public on Feb. 24, so stay tuned!
