Miley Cyrus' credit card was declined when she tried to purchase $170 worth of records.

The 21-year-old pop star was left red-faced when her card was allegedly refused by Freakbeat Records in Sherman Oaks, California, on Sunday (01.12.13) as she tried to pay for new items to add to her musical collection.

An eyewitness told RadarOnline.com: ''No one in the store really recognised Miley, even though she was hard to miss. It's not her demographic of fans. But she was embarrassed nonetheless when her card was denied.''

Thankfully for the 'Wrecking Ball' singer - who is thought to be worth over $100 million thanks to her pop career and Disney child star past in 'Hannah Montana' - she was able to whip out another credit card and complete her purchase.

The onlooker added: ''The cashier was really nice and told her the bank probably put a hold on it because it was a large purchase, so she dug out another card and the payment went through.''

Miley shared a picture of one of the vinyl records she picked up on Twitter - the soundtrack to 1978 film 'The Wiz', which starred one of her musical inspirations, Michael Jackson.

She captioned the picture: ''So stoked #thewiz (sic)''
