Adele is apparently a big fan of Celine Dion. The "Skyfall" hitmaker paid the "My Heart Will Go On" singer a top secret visit at her London gig on Tuesday, June 20. The two reportedly met backstage to have a private time and even discuss about having a duet on the show.

In the middle of her performance, Celine gave the crowd a subtle hint at Adele's visit. She said, "I want to move here. If I do, do you think if I move here I can meet Adele and you can help fix this for me?" The singer then shared that she had always wanted to sing with Adele, before belting out the 29-year-old songstress' hit song "Hello".

"Adele made trip to meet her idol and the music legends both embraced in a private room backstage before the gig and told each other how much they loved each other," a source told The Sun. "Adele said she would love to sing with her on stage at some point but she would be too scared."

While the two divas haven't decided to make a duet either in the studio or on stage, the possibility is still open. Prior to this, Celine admitted that she was a huge fan of Adele. She hoped that she could sing with the English singer as she sang a rendition of "Hello" with a little modification on the lyrics. "Adele, hello, it's me," the 49-year-old singer rhymed. "I was wondering if you can sing a song with me. Anywhere, any time."
