Life on the road can be a real drag for Miley Cyrus, especially when she's touring with her whole family - her brother uses her toothbrush to comb his hair.

The pop sensation insists she's got a tourbus routine that helps her live as normally as possible when travelling from gig to gig - but it's far from ideal.

She explains, "My brothers, sisters and I share one bathroom.

"My brother has a ridiculous haircut, and he'd use my brush but leave his hair in it.

"And he used my toothbrush to comb his eyebrows once."

But Cyrus always makes sure she gets a little pamper time to herself when she arrives at venues: "I ask for soap and two towels in my dressing room because I shower at the venue.

"I hate showering on the bus because my brothers use all the hot water."
