The 65-year-old singer thinks they are the perfect couple because they are so different, reported Contactmusic.
"They seem to be a really great couple, and they seem to really care about each other. I am just hoping for the best for them," she said.
"It would be great if that relationship really worked out and they were together forever. I think they're really good for each other. They're very different people, and that's the best way to go out with somebody," she added.
"I always love to dedicate 'Landslide' to people I know really get it and appreciate it. Because it doesn't go out to anybody," she added.
