Miley Cyrus was working on her birthday. She had a performance scheduled for the American Music Awards on Sunday evening hence the birthday girl decided to celebrate her birthday party after the award night. The "Wrecking Ball" singer turned 21 on Nov. 23 (Saturday) and had a big birthday bash which was attended by her friends and guys from One Direction!

The birthday party had strippers who danced in skimpy clothes, some of them wearing just thongs and shaking their booty with music. Two of the party goers even dressed like Miley and Robin Thicke were at the MTV Video Music Awards. Watch the video here.
