Miley Cyrus has splashed out on a $75,000 car for her 16th birthday.

'Hannah Montana' star - who reportedly earned $18.2 million last year - is treating herself to a "fully loaded" white convertible Mercedes Benz to mark the milestone on November 23.

A source said: "Miley wanted special options like parking assist and a cream-coloured leather interior, so she ordered the car early. She is telling everyone that she hopes to get a car when she turns 16, so when it comes, she can say it was a surprise from her parents."Sponsored Links:

Miley - the daughter of country singer Billy Ray Cyrus - recently revealed she wanted a "bad" car to celebrate turning 16.

She said: "I definitely want to get something bad on the road, big enough for all my friends and to scare all the cars away from me. I'm a good driver but it's everyone else that I'm worried about!"

Miley is set to celebrate her birthday at Disneyland, California, and is selling $250 tickets for the bash to raise money for Youth Service America.

Meanwhile, it has been claimed '7 Things' - which appears on Miley's current album 'Breakout' - was written about her split from Jonas Brothers singer Nick Jonas.Sponsored Links:

The catchy track, which features the young star detailing the seven things she hates about an unnamed ex-boyfriend, includes the lyrics, "Your friends, they're jerks/When you act like them, just know it hurts."

Miley parted ways with Nick in 2007 after two years together.

Earlier this year, 15-year-old Nick insisted the song wasn't about him, saying: "My friends aren't jerks."

However, Brett Ratner - who directed the video for '7 Things' - revealed the necklace Miley wears in the video was given to her by the boy she sings about.

He said: "She is wearing his diabetes or medical necklace. You can tell by the lyrics that they're very personal. The stuff she talks about in the video is clever and emotional and fun at the same time."Sponsored Links:

Nick has Type 1 diabetes and campaigns to raise awareness about the disease.
