Adele has described seeing Céline Dion at a recent show as a "full-circle moment".
During her Weekends with Adele residency show at The Colosseum at Caesars Palace in Las Vegas, Nevada on Saturday night, the Hello hitmaker singled out the Canadian music icon while singing her 2015 hit When We Were Young.
Adele proceeded to walk over to Céline and embrace her, with both superstars appearing tearful as they exchanged a few words.
Taking to Instagram on Monday, the English singer reflected on the emotional meeting and explained the significance of the venue, as the room was originally built for Céline's first concert residency in 2003.
"I have been performing in Celine Dion's room at the Colosseum for almost 2 years now," she began. "Four weeks to go! It was the only venue I wanted to play in Vegas because it was built for her. I have a picture of her right next to the stage that I touch every night before I walk on and she came to the show this weekend and it was a surprise and it was a MOMENT!!"
Adele went on to offer the My Heart Will Go On singer heartfelt thanks for surprising her at the concert.
"I love you so very, very much. Words will never sum up what you mean to me, or what you coming to my show means, let alone how it felt seeing you back in your palace with your beautiful family," the 36-year-old gushed. "I have loved being there it has been such an honor and Saturday night will be something I remember forever and ever. Such a full-circle moment for me to be there with you. Thank you so much."
Céline has not yet publicly responded to Adele's message.
However, several celebrities were quick to praise the sentiment.
"I'm not crying... you are," wrote Rita Ora, while Chrissy Metz commented, "Oh my goodness."
And Rita Wilson posted, "This is so full of love."
Adele is set to conclude her concert residency on 23 November.
