Jennifer Lopez sizzles in a cutout halter dress at the 'Wicked' premiere

Let's get loud for Jennifer Lopez's latest look.

The “Selena” actress stunned at the Los Angeles premiere of “Wicked” at the Dorothy Chandler Pavilion on Saturday night, wearing a skin-tight, beaded brown and cream dress by Zuhair Murad.

The dress featured a halter neckline, a high slit, and cutouts at the waist that left her lower back exposed.

Lopez, 55, paired the look with diamond-studded nude strappy sandals, pearl bracelets by SABYASACHI and a sparkling clutch.

She wore her hair loosely pinned up, with two curls hanging down in front of her face.

The “I'm Real” singer's hairstylist, Andrew Fitzsimons, noted on Instagram that Lopez's look was inspired by French actress and singer Brigitte Bardot.

“I started by doing a bouncy blow dry with my @wavytalkofficial Pro Quick Dry Hair Dryer, then sectioned the hair and attached my hair extensions in horizontal rows, one row towards the back of my neck and one row towards the front to create more volume .” He wrote on Saturday.

“Once the extensions were securely in place, I sprayed the hair with @andrewfitzsimonshair Après Sexe Texture Spray, pinned and twisted to create this effortless Bardot-style updo, and secured with bobby pins,” Fitzsimons added.

The hairdresser said he added two individual clip-ins to the front of Lopez's hair to add volume and “used my thermal brush to brush them backwards away from her face with her bangs.”

As for the “Mother” actress' glamour, her makeup artist Rokael Lizama said on Instagram that he used his “dazzling eyeshadows” that are “coming soon” to achieve that “J.Lo glow.”

Lopez's appearance at the “Wicked” premiere follows her press tour in London to promote her upcoming film “Unstoppable.”

To the film's premiere in London on Tuesday, the “Love Don't Cost a Thing” singer wore a white mohair halter dress by Magda Butrym ($1,220), a matching alpaca jacket ($3,900), wavy Christian Louboutin leather pumps ($845) and an ivory clutch.

And on Wednesday, the mother of two stepped out in a plunging bow-adorned mini dress and faux fur coat.
