Pop sensation Miley Cyrus has discovered fame comes at a high price — she’s too busy to attend her high school prom.

The “Hannah Montana” star, who co-hosted the CMT Awards with her father Billy Ray on Monday, was hoping to make it to the big dance, but has recently learned she won’t be able to get there.

She says, “I am shooting my movie during prom days, so I won’t be there.”

But the 15-year-old siner admits she’s secretly relieved — because she doesn’t have a date: “I would be like the single loner at the back of the prom. That’s the worst! I am not going to do that.”
