Miley Cyrus... 18!

Miley Cyrus on the Red Carpet of the 2010 AMA

Today is Miley’s (18) birthday. Last night she celebrate her birthday in the Hollywood club Trousdale. Miley was at the club for a post American Music Awards/ pre 18th birthday party and she pretty much partied till she dropped.

There were a lot of friends including her new boyfriend: A eighteen year old Canadian actor, Avan Jog, who has starred in a series of Nickelodeon shows and is now making the move onto the big screen. Miley and Avan were first linked together back in October when they were spotted heading out to lunch together and later attending a Halloween party.

She literally partied till she dropped down on the floor! Not only was Miley a Party Animal, She  kissed Avan in front of all her friends! Miley is acting more grown up last time and is not the old Hannah Montana anymore! Miley was not only acting older, she was also dressed in a pretty X-rated way too.

She was wearing a pair of skin-tight black leather trousers, black high heeled boots and a cropped black leather bra top, quite a far leap from her Hannah Montana days.

She stayed at the club until around 3 am.

The singer/actress had parent and alcohol awareness groups up in arms when she was pictured drinking a Corona beer earlier this month in a Madrid nightclub.

The legal age for consuming alcohol in Spain is eighteen, although authorities usually turn a blind eye and don't think underage drinking is a big issue.

It's a different scenario in the U.S. though, where the legal age for drinking is twenty-one and it is strictly enforced.

James E. Copple, the head of the International Institute for Alcohol Awareness expressed concern that other young people will follow Miley's lead and engage in 'risky behavior associated with under age alcohol consumption.'

Commenting: 'The young people that see her as a role model could mimic the same behavior and as a consequence will go out and become intoxicated, putting their safety at risk.'

Going on to note that, according to his organization, '85% of young people who drink, drink to get intoxicated.'

Miley has also been dressing in a pretty risque way recently too.

At the MTV European Music Video Awards Miley wore an extremely daring side less and backless white dress, which fully exposed her chest area when she posed on the red carpet.

Thankfully her hair was long enough to protect her modesty, but her under-the-chest tattoo was clearly visible.

Then last month Miley caused yet more controversy with the release of her video for her new song, Who Owns My Heart.

What do you think of the Can't Be Tamed-singer? Absolutely, She can't be Tamed!
