Adele burst into tears when she spotted Céline Dion in the audience at her concert over the weekend.
During her Weekends with Adele residency show at The Colosseum at Caesars Palace in Las Vegas, Nevada on Saturday night, the 'Hello' singer singled out the Canadian music icon while singing her 2015 hit 'When We Were Young'.
In fan footage posted on X, Adele becomes tearful before approaching Céline in the crowd.
As part of the exchange, the British star shared a few words with the My Heart Will Go On singer as she held her face in her hands.
Adele proceeded to wave at spectators before briefly speaking to Céline further. She then headed back to the stage.
Another clip showed the 56-year-old sitting down following the emotional moment and wiping away tears.
Céline appeared to be at the show with her 14-year-old twin sons, Nelson and Eddy.
The sweet reunion is a full circle moment for the pair, with Adele having attended one of Céline's concerts at the same venue back in January 2018.
In a post shared via Instagram at the time, 'The Power of Love' hitmaker gushed over meeting the 36-year-old at the gig.
"Wasn't able to do all my shows, but was thrilled that Adele came to one of them... I love her so much!!" she praised.
Accordingly, Adele returned the compliment by writing a message on her own account in which she exclaimed: "Queen Celine! What a show, an absolute highlight of my life, thank you so much for the attention to your crowd and insane humor. Happy new year lady (sic)."
Adele is set to conclude her concert residency on 23 November.
