Miley's raising money for the Pappy Cyrus Family Foundation (named after her grandpa), which was set up to support underprivileged children.
The date with Miley is currently sitting around the US$2,000 mark - is it a small price to pay to hang out with a tween superstar?
The winning bidder gets to go to the premiere of upcoming Disney film Bolt and meet up with Miley in person. No word on whether they get to actually have a 'date' with her, though!
