Christina ‘Xtina’ Aguilera officially kicked off her 10-date Las Vegas residency at the brand new Voltaire Belle De Nuit located inside The Venetian Resort and Casino in Nevada on Saturday night.

The 43-year-old R&B belter had over 10 costume changes, selected by stylist Chris Horan, throughout the sold-out show inside the ‘seductively cozy’ 1K-seat key-hole themed theater.

Christina’s sexiest get-up was a black strapless PVC leotard designed by Anthony Ladd Canney and matching thigh-high boots she wore on a bed (a la Madonna) to perform a cover of Lesley Gore’s 1963 hit You Don’t Own Me.

Aguilera wore the same outfit to use her unmistakable four-octave soprano pipes to perform her 2002 raunchy hit Dirrty.

The five-time Grammy winner opened her concert perched on a platform while wearing a towering long red Dawna Oak gown, which cascaded on to the stage while belting her 2010 song Not Myself Tonight.

Grace Jones originated the mountainous dress idea during her 1986 music video for I’m Not Perfect (But I’m Perfect for You), and Björk took the stunt even further performing at the 2004 Summer Olympics in Greece.

The Staten Island-born, half-Ecuadorian singer waved around a crystal-looking ornamental branch and, of course, wore a double-strand diamond necklace for the number.

Christina wore a glittery silver mini-dress to perform a cover of Christophe Beck’s 2010 song Welcome to Burlesque, which was famously originated by her Burlesque co-star Cher.

Aguilera continued to wear the dress with black opera gloves and thigh-high boots to sing her 2006 hit Ain’t No Other Man as well as her 2010 cover of Ralph Rainger’s 1933 song Guy What Takes His Time.

And the Learning to Fly songstress added a pair of large sunglasses to perform Bob Crewe and Kenny Nolan’s 1974 Labelle track Lady Marmalade, which she famously covered in 2001 alongside Lil’ Kim, Mýa, and Pink.

Christina wore a strapless silver midi-dress to sing her 1999 breakout single Genie in a Bottle as her back-up dancers wrapped her with rope.

Aguilera wore a black feathered Mugler catsuit as she sat on a diamond-shaped chair to perform a cover of John Barry and Don Black’s 1971 Bond theme Diamonds Are Forever (made famous by Shirley Bassey).

The platinum-blonde pop diva then joined her dancers on the catwalk to perform her 2010 track Glam while wearing the same all-black sheer costume.

‘I look forward to bringing Las Vegas a new show that fuses music, sophistication and art in ways I have never performed before,’ Aguilera told Billboard in a statement back in October.

‘What I love about the intimacy at Voltaire at The Venetian Resort is how up-close-and-personal I can be with the audience… a truly modern twist on the performance experience.’

The La Reina singer’s last Las Vegas residency – Christina Aguilera: The Xperience – at Planet Hollywood’s Zappos Theater ran for 24 concerts and grossed $10.2M in 2019-2020.

Christina donated one dollar from every ticket purchased to The Shade Tree, a 24-hour accessible emergency shelter in Southern Nevada for women and children in crisis.
