Other celebrities including Katy Perry, Kendall Jenner and Hailey Bieber also attended the concert.

It comes after Christina Aguilera joined Sabrina on stage during another LA stop on her Short n’ Sweet tour on Friday night.

The 43-year-old iconic pop star — who recently shared pH๏τos with her family — joined the 25-year-old songstress on stage as they performed renditions of Aguilera’s songs Ain’t No Other Man and What A Girl Wants.

DailyMail.com obtained images of the epic live collaboration at the Crypto.com Arena in downtown LA.

Both bombshells wore their platinum blonde locks in long, silky curls that fell over their shoulders.

For her unexpected appearance, Christina showed off her slimmed down frame in a busty black corset and shorts.

The mother-of-two, who was raised in Pittsburgh, added thigh-high sparkly silver boots while wowing the audience with her signature pipes.

She looked great with a glinting diamond necklace and matching chandelier earrings.

For her part, Sabrina also opted for a Sєxy black look as the Bed Chem hitmaker strutted out in black lace capris, Mary Jane shoes, and a sparkly black robe.

Concertgoers shared footage of Christina and Sabrina’s stage time on X (formerly Twitter) during Friday night’s concert.

The two music artists previously teamed up for a 25th anniversary celebration of the Genie In A Bottle hitmaker’s self-тιтled debut album.

The industry fixture, who rose to fame in the late 90s alongside acts like NSYNC and Britney Spears, participated in a live studio re-imagining of her debut album for an episode of Spotify Anniversaries in September.

In addition to Sabrina, she was also joined by Machine Gun Kelly for updated iterations of her old music.

At the time, Christina told Rolling Stone , ‘I wanted to celebrate the 25th anniversary of my debut album in a way that brings together the past and present.’

She added, ‘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.’

The former Mickey Mouseketeer reflected, ‘I laughed, I cried, I reconnected with old friends, and I made some very special new ones.’

And she told fans, ‘I hope this anniversary gift is just as special for you to watch, as it was for me to make.’

Carpenter’s tour kicked of on September 24, 2024 and is slated to run through March 26, 2025.

On Thursday night she shared pH๏τos from the tour on Instagram and wrote in a caption to her 42 million followers: ‘tomorrow we start our last 3 shows of the US leg in Los Angeles. I can’t wait to see you all there.’
