Miley Cyrus, 'We Can't Stop' Lyric Confirmed as 'Molly' Drug Reference: Demi Lovato Looks Out for Former Disney Co-Star, Is Liam Hemsworth's Fiancé Partying Too Much?

Miley Cyrus really can't stop trying to prove that she's all grown up now. Rumors have been floating that the former Hanna Montana star's new hit single "We Can't Stop" is rife with drug references. Though "trying to get a line in the bathroom" is a little more obvious, one contested lyric finally has an answer. Is it "Dancing with Miley" or "Molly?" Cyrus has revealed she's singing about rolling on molly, though she smartly remained somewhat sly.

"It depends on who's doing what. If you're aged 10, it's 'Miley,' if you know what I'm talking about then you know," Cyrus told the Daily Mail. "I just wanted it to be played on the radio, and they've already had to edit it so much."

Cyrus has had no shame about showing how much she's grown. Her controversial video for "We Can't Stop" shows the starlet throwing a wild party for her friends, and includes Cyrus grabbing women's behinds, writhing around on a bed while chewing gum and making a lewd oral sex gesture.

"I don't think people have a hard time understanding that I've grown up," Cyrus said. "You can Google me and know what I'm up to -- you know what that lyric is saying."

Though her Smilers stand firmly behind the singer, one of Cyrus' former Disney contemporaries is a little worried about her.

In an interview with MTV News, Demi Lovato revealed that she feels "protective" of Cyrus. Lovato, who has had issues with substance abuse and mental health, told MTV: "She knows how I feel about the whole partying thing. I love her to death, and I'm always like 'Just be careful," and she's like, 'Dude. I'm chilling. It's fine.' But I care for her so much that I'm so protective, but she's good. She's got a good head on her shoulders."
