Christina Aguilera Poses in Nothing But Her ‘Birthday Suit’ For Sultry 44th Bday Pic

It’s less than a week before Christmas, but Christina Aguilera has already unwrapped a big present. The singer wished herself a happy 44th birthday on Wednesday (Dec. 18) by posting a sultry pic celebrating herself in which she’s wearing nothing but a sly look, black leather hat, matching hot pants and strappy stiletto heels.

With her right hand covering her bare breasts and her left hand resting on her bare thigh, Aguilera captioned the black and white snap “Birthday Suit #44.” A number of fans commented that the vibe was similar to XTina’s look in the 2010 musical Burlesque, in which she co-starred with Cher as a rising singer name Ali.

Back in September, Aguilera celebrated the 25th anniversary of her self-titled debut album by teaming up with Spotify for one of its Spotify Anniversaries series to reimagine her 1999 LP with a number of special guests. The 26-minute session included Aguilera collaborating with MGK for a revamp of her breakthrough hit “Genie in a Bottle,” as well as reuniting with producer Ron Fair and songwriter Heather Holly for a new version of the song “Obvious.”

The highlight of the look back was Aguilera dueting with fellow pop star Sabrina Carpenter for a vocal master class run through another one of Christina’s iconic hits, “What a Girl Wants.” Carpenter returned the favor on Nov. 15 when she invited Aguilera out to sing XTina’s classic hits “Ain’t No Other Man” and reprise their “What a Girl Wants” collab during the “Espresso” singer’s Short n’ Sweet Tour stop at L.A.’s Crypto.com Arena.
