She has been dressing much older than her age for quite some time now.

And as of this month Miley Cyrus will be able to wear all the see-through, leather and low-cut outfits she likes without causing a storm of controversy.

The soon-to-be 18-year-old, who reaches the milestone on November 23, was still raising eyebrows last night though when she performed in a sheer white dress that put her underwear on full display.

Racy: Miley Cyrus performed on German TV show Wetten, dass…? last night in a see-through white dress.

The revealing dress, made of white tulle material was completely see-through except for a design that slightly covered her stomach and chest.

The Hannah Montana star wore flesh-coloured body stocking beneath but her underwear was still obvious as she performed her new single Who Owns My Heart on German TV show Wetten, dass…?

To add to the risqué performance, Miley gyrated through a provocative routine with her back-up dancers, before settling in for a chat alongside actor Denzel Washington, appearing to promote new film Unstoppable.

The popstar has returned to Madrid today after her brief stint in Germany, where she will perform at the EMA Awards.

Miley has remained tight-lipped about her performance, but hinted yesterday that it will feature an ‘Angels and Demons’ theme.

She told MTV News at rehearsals in Madrid on Friday ‘It’s [about the idea] that during this world, you’re always going to have temptation. Basically that’s kind of the whole vibe.’

The Party in the USA singer has been in the Spanish capital ahead of the EMA Awards, and held a fan event on Friday before heading to a bar with friends in the evening.

She was criticised in the US, where the legal drinking age is 21, when she was spotted drinking a Corona beer at the bar, but she was not breaking any laws as the legal drinking age of 18 is a somewhat relaxed rule in Spain.

Miley also revealed her desire to spend quality time with her family for her milestone birthday.

Her parents Billy Ray and Tish Cyrus are currently going through a very public split, with allegations emerging this week that Tish had an affair with Bret Michaels.

Tellingly, Miley said of her birthday plans: ‘I’m not going to go crazy. Just have a fun party and then maybe take a vacation with my family … because that would be really cool. I think we need time to all be together.’

She added: ‘That would be rad if we could all go to the beach or something. [I have] no idea [where we’re going]; somewhere near water. I’m a water baby – I have to be near the water and I love doing scuba and going out and being on a boat.’
