Miley Cyrus is one busy girl.

She’s managing a singing career, an acting career, a relationship with a 20 year-old “straight” underwear model, and even goes to school.

Well, we bet she’s home-schooled. Somewhat. Doubt she’ll pass her GED - but that’s for another post 3 years from now.

Slutty Cyrus was in Berlin, Germany, yesterday to promote her album, Breakout. On Monday night, she performed for the Germans with a FABULOUS concert.

And like a good Christian girl, she made sure to wear her “promise ring.”

We doubt Justin Gaston bought her that ring, though. You know Miley’s the sugga momma in that relationship!
