Mariah wowed fans with her headline set at the Essence music festival, which was held at the Louisiana Superdome.

She belted out her most famous hits, but all eyes were on her saucy costumes.

The Hero star made a number of costume changes throughout her set, but it was her sparkly silver gown that drew the most attention.

The singer’s breasts came close to spilling out of the super-tight frock as she leaned down to hit one of her infamous high notes.

She also showed a lot of leg as her dress was cut almost all the way to her waist.

During the show, Mariah raised temperatures by bringing out a troupe of hunky dancers, who lifted her on a sofa.

The singer narrowly managed to preserve her modesty as her dress fell open to expose her thighs.
