Could this explain Miley Cyrus's wild performance at last Sunday's VMA's?
In an interview with Sunday People, Miley reveals to the UK paper that she is "messed up" and sometimes sleeps for only 45 minutes night.
“I don’t have a normal life," says the 20 year-old. "I take a hiatus every now and again but I’m not good at that.”
5 Things We Learned from Miley Cyrus' VMA Performance
“I have so many f***ing issues. I am so f***ed up – everyone does dumb stuff when they are messed up."
The paper says they conducted the interview five weeks ago when Miley was in the county promoting her hit single 'We Can't Stop.'
Miley's performance of the song, and her 'Blurred Lines' duet with Robin Thicke, at the awards show shocked fans around the world and set a new Twitter record.
She has yet to comment publicly on her racy VMA appearance but her Twitter feed suggests she's pretty excited by all the attention it drew.
And it's not hurting sales either: Since last week her new single Wrecking Ball has been downloaded more than 90,000 times.
