The 'My Heart Will Go On' star, who covers 'Rolling in the Deep' at her Vegas show, described Adele as "refreshing".
"I love literally everything about her," Dion told Vegas magazine. "I love her extreme talent. I love her writing. Her songs come from the soul.
"She's incredibly beautiful. I think it's very refreshing to see, and don't get me wrong when I say this, somebody who is not looking extremely anorexic.
"She is going to help us, she's going to help the world. It's going to be bad when I meet her. I'm going to give her the biggest hug. I'm not kidding."
Dion is reportedly planning to release two new albums this autumn.
