Having a credit card declined happens to even the most financially responsible of us (those darn machines!) but to a multi-millionaire? Seems a little less likely! But not in the case of Miley Cyrus. The recently 21-year-old may be worth more than $150 million but that doesn’t mean her plastic’s made of gold.

Miley had her credit card denied this weekend after trying to buy $170 worth of records in Sherman Oaks, California, according to a RadarOnline.com report. The Head Smiler, wearing “super short shorts and a tight leather jacket,” is said to have been at Freakbeat Records on December 1 looking to stock up on some new tunes, but when she got to the counter to check out, her card was turned down.

An “eyewitness” source tells Radar, “No one in the store really recognized Miley, even though she was hard to miss. It’s not her demographic of fans. But she was embarrassed none the less when her card was denied.”

Um, yeah. We would have been too and we’re not even international pop stars! Thankfully, the source says the cashier was “really nice” and told Miley her bank probably just put a hold on her card because it was such a large purchase ($170 for a millionaire?). Miley just ended up using another card and, that time, Radar’s source says “the payment went through.”

As for the pop diva, she didn’t seem much fazed by any kind of financial hiccup. That same afternoon she tweeted a photo of an iconic Michael Jackson movie soundtrack, presumably from her run to the record store. “So stoked #thewiz,” she wrote. Who doesn’t seem so stoked? Her bank.
