Miley Cyrus' sweet 16 birthday party on Sunday wasn't all smiles for the teen star - she has had her credit card confiscated for six months.

The Hannah Montana star celebrated her birthday six weeks early with a special party at the Disneyland themepark in California.

And, after she was gifted with a pet dog, her parents took away her beloved credit card.

Her stepmother Leticia swiped the plastic after discovering Cyrus had overindulged.

Speaking at the party, Leticia reveals, "She had a credit card, and she went a little over her limit the other day, so I said, 'No credit card for six months.'"
