Christina 'Xtina' Aguilera began her 10-date residency in Las Vegas on Saturday night at the brand-new Voltaire Belle De Nuit, which is housed inside The Venetian Resort & Casino in Nevada.
The 43-year-old R&B singer changed into around ten different outfits during the sold-out performance at the "seductively cozy" 1,050-seat theater with a keyhole theme, all chosen by stylist Chris Horan.
The complete setlist for this night includes:
1. Not Myself Tonight
2. Your Body
3. Diamonds Are Forever
4. Glam
5. Vanity
6. Genie in a Bottle
7. You Don't Own Me
8. Dirrty
9. Guy What Takes His Time
10. Ain't No Other Man
11. Welcome to Burlesque
12. Lady Marmalade
13. Fighter
14. Beautiful
15. Diamonds Are a Girl's Best Friend
According to Daily Mail UK, which gave a rundown of this night song by song, Christina looked amazing when she sang a cover of Lesley Gore's 1963 hit song You Don't Own Me on a bed, dressed like Madonna in a black, strapless PVC leotard and matching thigh-high boots.
Aguilera performed her 2002 raucous smash Dirrty while dressed identically and showcasing her distinctive four-octave soprano pipes.
The five-time Grammy winner sang her 2010 hit song Not Myself Tonight as she began her performance while seated on a platform and dressed in an incredibly long crimson Dawna Oak gown that flowed onto the stage.
The idea of the mountainous dress was first introduced by Grace Jones in her 1986 music video for the song "I'm Not Perfect (But I'm Perfect for You)."
Björk then carried the prank to new heights when she participated in the 2004 Summer Olympics in Greece. Christina also sang her 2012 single Your Body, flashing her 5ft 2in physique in a halter-neck nude leotard and white thigh-high boots.
When Aguilera sang a performance of Leo Robin and Jule Styne's 1949 Broadway song Diamonds Are a Girl's Best Friend (made famous by Marilyn Monroe), she looked amazing in a light-up blue dress and black leather thigh-high boots.
The vocalist, who is partly Ecuadorian and was born in Staten Island, waved a decorative branch that had a crystal appearance during the song. She was obviously wearing a double-strand diamond necklace.
Christina sang a cover of Christophe Beck's 2010 song Welcome to Burlesque, which was notably first performed by her Burlesque co-star Cher.
Christina was dressed in a shimmering silver minidress. Aguilera wore the outfit with black opera gloves and thigh-high boots while performing her 2010 cover of Ralph Rainger's 1933 song Guy What Takes His Time and her 2006 hit song Ain't No Other Man.
The singer of Learning to Fly also donned a big pair of sunglasses as she sang Lady Marmalade, a 1974 Labelle classic by Bob Crewe and Kenny Nolan that she notably recorded with Lil' Kim, Mþa, and Pink in 2001. When Christina sang her 1999 hit song Genie in a Bottle, her backup dancers wrapped her in rope while she donned a strapless silver mididress.
Aguilera sang a performance of John Barry and Don Black's 1971 Bond theme Diamonds Are Forever (made famous by Shirley Bassey) while sitting in a chair shaped like a diamond.
She was dressed in a black feathery Mugler catsuit. Wearing the same all-black sheer gown, the platinum-blonde pop singer then joined her dancers on the catwalk to perform her 2010 song Glam.
