R&B queen Mariah Carey debuted her new single at the 2014 BET Honors, which was being taped Saturday (Feb. 8) at the Warner Theatre in Washington, D.C.

The seventh annual event was being held to salute Aretha Franklin, Berry Gordy, Jr., Ice Cube, the late Nelson Mandela and others for their achievements in their respective fields.

Mimi, who was honored at the 2012 BET Honors, performed her new song 'You’re Mine' atop a grand piano. The veteran singer wore an all-black grown that revealed her enormous cleavage. Afterward, she was greeted with a big hug from her daughter Monroe.

Other highlights from the event included Aretha Franklin's granddaughter, Victorie Franklin, performing Tamela Mann's 'Take Me to the King’ to honor her grandmother. That was followed by a fantastic tribute by Oscar-winning songbird Jennifer Hudson.

Later, the Queen of Soul, herself, grabbed the mic to perform a powerful song in honor of the late South African president Nelson Mandela.

Elsewhere, rapper/film mogul Ice Cube was presented with his BET Honor by fellow rapper-actor Ludacris who, we must say, cleaned up well in his tailored suit.

During Berry Gordy, Jr.’s tribute segment, audiences were treated to a medley of hits from the Motown catalog. Tamar Braxton, dressed in a gorgeous purple dress, sang Diana Ross’ classic song 'Upside Down.' Janelle Monae gave an energetic performance of The Jackson 5’s 'I Want You Back' and Smokey Robinson performed the tender ballad 'Tracks of My Tears.'

Overall, it was a great night of black excellence.

"I can NOT lie @bethonors was just about as #EPIC as the BEST NIGht EVER!!," Tamar tweeted to her fans. "Thank you all @bet [I love] my TV family."

The 2014 BET Honors, with host Wayne Brady, will air on Feb. 24 at 9PM ET.
