Pop icon Madonna showed off her sexy side by donning a skimpy outfit to celebrate her 55th birthday at a lavish costume party on Saturday (17Aug13).

The Material Girl, whose big day was on Friday (16Aug13), made sure all eyes were on her by turning up dressed as French queen Marie Antoinette in a sexy purple corset, a heart-shaped eye patch, fishnet stockings and a towering blonde wig.

Madonna drank Champagne and partied with her boyfriend Brahim Zaibat and daughter Lourdes, and was later presented with a five-tier pink cake decorated with sparklers at the extravagant bash, held in the south of France.

Madonna later posted snapshots of the evening online and tweeted, "Perhaps we had too much cale (sic)! But at my birthday party all I could see was love," before adding, "Perhaps I had too much Champagne! I meant to write cake!"
