Miley Cyrus catches heat for new single

Miley Cyrus arrives for the 21st annual Elton John AIDS Foundation's Oscar Viewing Party Feb. 24, 2013, in Hollywood, Calif.

It's been a while since we've seen that "Hannah Montana" side of Miley Cyus. But her latest single, "We Can't Stop," released this week, is another reminder that Cyrus has definitely shed that high school image.

The 20-year-old singer's new single, which shot to No. 1 in its first day on iTunes, is definitely not "Party in the U.S.A." Actually, she appears to be singing about a way different kind of "party."

Twitter was all abuzz Wednesday with talk that Cyrus appears to be referring to drugs in the lyrics to the new pop track, with hints that the following lines refer to cocaine: "Everyone in line in the bathroom/Trying to get a line in the bathroom/We all so turnt up here/Gettin' turnt up yeah yeah."

And then there's the possible Ecstasy reference; "Molly" has been equated with the drug: "La-da-di-da-di/We like to party/Dancin' with molly/Doin' whatever we want."

We get it, Miley. You are all grown up. Strip club dancing and all. Which brings to mind yet another line in the new track: "My home girls here with the big butts/Shaking it like we at a strip club."

On the day of its release, Cyrus tweeted: "#wecantstoppremiere can't believe it's finally here! Ahhhh." She just shot an official video for the song.

And Cyrus, who doesn't expect to release her album until the fall, promises more songs soon. It will mark Cyrus' first new album 2010's "Can't Be Tamed."
