In one image, uploaded to her Instagram on Halloween, Grande could be seen with stripes of gold glitter in her high ponytail as she rocked a pale pink robe over a sheer nude leotard.

The two-time Grammy winner also rocked a dramatic winged white liner, dazzling gems around her eyes and a pair of dangly pearl earrings.

Flawless: While dressed the raunchy cult classic’s main protagonist, the 30-year-old singer was nearly indistinguishable from Elizabeth Berkley (seen above in 1995), who portrayed the fictional Las Vegas transplant that becomes one of Sin City’s top showgirls, in the controversial NC-17 rated film

The Scream Queens star and her former Victorious costar, also 30, nailed several other looks from the legendary Hollywood bomb.

Gillies shared an image of them both rocking black leather jackets and a cheeky shot of herself shaving her legs in a see-through, purple robe with feathers on the cuffs.

Gillies was a dead ringer for Cristal Conners (Gina Gershon) with her beautiful brunette locks styled in a wavy updo while smiling into the camera.

‘You are a wh**e, darlin’,’ Gillies captioned her post, referencing a line her character told Grande’s.

The pair also shared a multiple videos, in which they recreated scenes from the film, which included one of Grande’s character insisting she is not a ‘wh**e.’

‘You and me, we are exactly alike,’ Gillies retorted.

‘I’ll never be like you,’ Grande said, before throwing champagne in Gillies’ face.

Grande made sure to share bloopers of them breaking character as they attempted to film through their laughter and struggle to keep a straight face.

Gillies and Grande first met while working on the musical 13, which made its Broadway debut in 2008.

The friends went on to land roles in Victorious, with the Dynasty actress portraying Jade West and the Thank U, Next singer playing Cat Valentine.

The two remained with the show for all four of its seasons, which were aired between 2010 and 2013.

Grande reprised her role in the short-lived spinoff series Sam & Cat, although the program only consisted of a single season.

In 2013, Gillies was featured on the singer’s EP Christmas Kisses, where they performed a duet of the holiday standard, Santa Baby.

Gillies was featured in Grande’s Thank U, Next music video.

The actress later made an appearance during one of the hitmaker’s concerts in 2019, where they performed a track from Victorious.

Earlier this year, Grande penned a heartfelt birthday tribute to Gillies as she called her ‘the most beautiful, brilliant, talented, funniest person’ she has ‘ever met.’

‘You have made my heart so unfathomably happy and whole these past 16 years! Absolutely everything and also, absolutely nothing has changed. I love you more than words can possibly express and I hope we can be best friends in every life,’ she gushed.
