The teenager tells heat this week that she's struck up a surprising friendship with 54-year-old Mary Bryne, who was controversially eliminated ahead of Cher in the live shows in 2010.
Cher raved: "[Mary]'s the bestest thing ever!
"She's the most genuine person I've met in my whole life. There's nothing fake about her - she is what she is and she's loving it."
But Cher explained how she hasn’t spoken to anyone else from her year, including One Direction.
"No, not really," she explains. "We're all busy doing what we do."
Cher's new single Want U Back is out now.
