Christina Aguilera Looks Like a Literal Disco Ball in a Plunging Corset Gown While Sharing Rare PDA With Her Fiancé

Christina Aguilera was sparkling like a mirrorball as she explored Paris by night for her upcoming holiday concert movie, Christina Aguilera: Christmas in Paris. As the “Genie in a Bottle” singer prepares to celebrate the 25th anniversary of her My Kind of Christmas album, Aguilera competed with the Eiffel Tower’s “sizzle” in a plunging, sequin-encrusted gown and knee-length mermaid waves in a trailer video shared on November 18.

The Burlesque actress brightened up an evening along the Seine River as she ran through Paris in a disco ball-coded gown that reflected light from every angle. Reinforcing the reputation of France’s capital as the city of light, Aguilera could be seen posing with her head leaning back over a terrace, twirling in place, and skipping down a bridge as the lit-up Eiffel Tower glittered behind her. The “Dirrty” singer brought some showgirl energy as she posed in a glittering mermaid corset gown that featured a sequin-encrusted white bodice, barely-there spaghetti straps, and a multi-tiered petal-inspired skirt trimmed with black lace at the hem.

As Aguilera turned, she showed off a black velvet sash that cinched her waist, as well as a black undergarment that added some additional coverage to her plunging dress’s completely backless design. A pair of black flats could be seen peeping out from under the mom-of-two’s trailing skirt.

Wearing her white-blonde platinum hair in glamorous, middle-parted mermaid waves that reached all the way down to her knees, Aguilera kept the lit-from-within ethos going with a glowing complexion, shimmering white eyeshadow, and a nude lip.

The star, who’ll be performing her biggest hits as well as Christmas classics against vignettes of Paris in the limited-release concert film, cosigned Paris as the city of love with some sweet nods to her longtime romance with fiancé Matthew Rutler. Aguilera could be seen adding an iconic love lock to a bridge before the camera panned to her sharing a sweet moment of PDA with the musician. The star could be seen making a kissing face at the screen and closing her eyes as Rutler embraced her from behind and planted a sweet kiss on her forehead.

Fans can see more from Aguilera’s Paris adventures, including Burlesque-inspired performances from the legendary Crazy Horse cabaret, when Christina Aguilera: Christmas in Paris is released on December 14 and December 21.
