"It sounded like a little kid," Miley told Access Hollywood's Billy Bush in an interview for Access and "The Billy Bush Show" of the "Baby" singer's recent late-night prank call. "I was like, 'Oh my gosh, I am so mad.' Then I get a text, he's like, 'Haha.'"

However, Miley told Billy that she wound up laughing, too.
"I have him in my phone as Bieber Fever, so that's always pretty funny when you get one of those [texts]," she said.
The "Can't Be Tamed" singer said she can't prank Biebs back – thanks to her little sister Noah's crush.
"I can't really be mean because my little sister is like, never ever going to have a boyfriend until it can be Justin Bieber," Miley said. "She's saving herself for the Biebs."
And Justin's not the only one with a nickname in her phone.
"My little sister is Mrs. Bieber in my phone," she added.
