Adele Shares Her Quirky Pre-Show Ritual Involving Celine Dion

Adele had the night of her life on Saturday when she welcomed Celine Dionto the stage at The Colosseum at Caesar's Palace in Las Vegas.

The "My Heart Will Go On" singer took in one of Adele's final shows at her longtime Las Vegas residency.

Adele tearfully noticed the singer in the audience and is now letting her fans and Instagram followers know how moved she felt by the life-altering moment!

Adele was in the middle of performing on Saturday night when she saw Dion from the stage. The duo embraced, and the "Easy on Me" singer cried tears of joy.

The audience was seemingly equally as moved by Dion's presence. The "I'm Alive" songbird received a standing ovation!

Adele shared a snapshot of the heartwarming moment on Instagram on Monday. Dion is seen lovingly cradling her friend's face as Adele happily cries, touched by the moment.

The "Oh My God" singer opened up about the lovely moment, sharing her feelings about how personally impactful it felt to see Dion in the audience watching her show!

Adele wrote, "I have been performing in Celine Dion’s room at the Colosseum for almost 2 years now. 4 weeks to go! It was the only venue I wanted to play in Vegas because it was built for her," she explained.

"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!! @celinedion 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."

Adele concluded, "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."

Celebrities like Chelsea Handler and Maren Morris celebrated the moment as well by liking the post.

Seeing Dion having a good time at her show seems to be a highlight in Adele's life lately.

You take the good, and you take the bad...the singer revealed she had been dealing with an ear infection, leaving her "a bit blind" in her left ear.

"It is the most painful thing that ever, ever happened to me in my life. It was worse than childbirth," she told the crowd at her Friday night show, per Us Weekly. The nuisance of having an ear infection is a new one for the singer: she also revealed she's never had an ear infection before.

The infection had been contracted in quite a unique way, from a "rare water bacteria" while on tour in Germany earlier this spring.

Thankfully, after a search for the right antibiotic, the singer told her audience she's no longer suffering.

"It is hard to treat, so I was on the wrong antibiotics for a few days," Adele told the crowd. "They managed to give me one that started to work. I’m no longer in pain, which is great, [but] I’m a bit deaf in my left ear," she explained.

Adele may have delivered some of the most beautifully sung ballads of the last decade, but that doesn't mean she has no time to listen to a catchy tune or two!

The "Rolling in the Deep" singer revealed she really enjoyed one of the summer's biggest chart-toppers: She told a crowd how much Sabrina Carpenter's monster hit "Espresso" is her "jam!" She also revealed the song had been stuck in her head before drifting off to sleep one night.

The hilarious moment was captured on TikTok.

Adele has heard the roaring of audiences for a long time in Vegas and soon she'll be hearing wedding bells!

The bride-to-be got engaged to her boyfriend Rich Paul last summer. Paul proposed with a four-caret diamond, during a planned hometown proposal.

Before Paul actually popped the question, some of the singer's fans thought the pair had already tied the knot. Their so-called "marriage" has been an "inside joke" between the couple, according to The Sun. Adele thinks the mistake is "hilarious," the publication reported.

Tickets for the final dates of Adele's Las Vegas residency are now on sale.
