Miley Cyrus uses a drip to boost her energy levels.

The 'Wrecking Ball' hitmaker has revealed she and her friends use an IV drip at home as a means of pumping nutrients into their blood in order to perk them up.

Miley, 22, appears in some behind-the-scenes photos with the IV attached to her arm, while in other pictures posted on Instagram the pop star's friends can be seen getting the same treatment.

Other famous names said to be fans of the unusual treatment include Rihanna and Madonna.

Meanwhile, Patrick Schwarzenegger is reported to have recently bought Miley more than 100 roses to win her back.

The actor was photographed getting close to his ex-girlfriend in Cabo San Lucas, Mexico but has reportedly treated his pop star girlfriend to some romantic dinners and expressed his love through e-mails.

A source explained: ''He was devastated when he thought she was going to dump him and really brought out the big guns to win her back.

''He bought her over 100 roses in assorted colours, he took her a number of amazing, romantic dinners, and more than anything he poured his heart out in a series of long emotional emails.''
