Shakira's Super Sleuth Challenge

Shakira has set her fans an online treasure hunt challenge - to give them the chance to win tickets for her exclusive album launch party.

The Colombian pop star's latest album, She Wolf, hits stores later this month and the sexy singer is hosting an intimate bash in Berlin, Germany in November to celebrate its release.

And one lucky fan could be there - if they solve a number of clues Shakira has started posting on social networking website Facebook. The clues will appear daily until Sunday.
