Miley Cyrus Celebrates New Single Reaching #1 On Itunes Chart

She's got a lot to be smiley about!

Miley Cyrus just released her single "We Can't Stop", and it has already climbed up the iTunes charts at lightning speed!

Currently at the #1 spot, the tune has spread like wildfire on social media sites, and the singer couldn't be happier about its success. The blonde beauty promoted her single all over Los Angeles yesterday, and tweeted some cute pics with her fans.

"#wecantstop is #1 on iTunes! Thank you sooooo much Smilers! I am so happppppy," she tweeted about the song release.

The jam contains some edgy lyrics that suggest the former Hannah Montana star is looking to break out of her good girl image.

"La-da-di-da-di, we like to party/Dancing with Molly," reads one portion of the lyrics, which many believe is a reference to the party drug ecstasy.

It's the song of the summer!
