The bilingual performer, who is known for her powerhouse vocals after rising to fame following the release of her hit track Genie in a Bottle, captioned the post: 'HELLO?!'

Earlier this week, Aguilera confirmed she would be releasing live studio re-imaginings of her debut album for an episode of Spotify Anniversaries, which will be released on September 23. 

'I wanted to celebrate the 25th anniversary of my debut album in a way that brings together the past and present,' she told Rolling Stone. 'I've always enjoyed reimagining my songs with different styles and audiences, as well as playing with sounds and arrangements that showcase how all music can be timeless.' 

In addition to getting some help from MGK, the mother-of-two also teamed up with Sabrina Carpenter on one of the tracks.

She noted that recording this project was 'both magical and nostalgic' and had her look back on some of her 'sweetest career memories.'

'I laughed, I cried, I reconnected with old friends, and I made some very special new ones,' she continued. 'I hope this anniversary gift is just as special for you to watch, as it was for me to make.'

Aguilera's first career started out when she competed on Star Search, before being selected for The All-New Mickey Mouse Club. 

After hanging up her mouse ears in 1996, Christina recorded the theme tune for Disney movie Mulan which helped propel her to fame with her self-titled debut album the following year. 

The album debuted at number one on the Billboard 200 chart, with help from her hit singles Genie in a Bottle, What a Girl Wants and I Turn to You.

In May, it was revealed that Christina was moving on from the only record label she's ever signed to, RCA Records, after 26 years.

Now Christina has signed 5020 Records, a Latin-infused label based out of Miami, according to Variety. 

Neither the singer, nor her former or new record label have spoken publicly about the shift, though a rep for 5020 confirmed Christina signed with the label.

Fans had speculated about the record label shift over the past few months, when the 5020 logo appeared on her website.

Her name has been quietly removed from the RCA website's Artists page, officially bringing an end to their 26-year collaboration.

Christina was discovered by RCA executive Ron Fair, after he heard her demo tape cover of Whitney Houston's Run It to You in 1997.

The $1 million that the label invested in Christina paid off when her first single Genie In a Bottle was released in May 1999.

The song spent five straight weeks atop the Billboard Hot 100 singles charts and became the second-highest-selling single of 1999, behind just Cher's Believe.

Her first album sold more than 10 million copies in its first year and was certified eight-time platinum, while also winning the Grammy for Best New Artist (seen in 2024)
