The singer wished herself a happy 44th birthday on Dec. 18th 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.
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.
