Madonna dons "Game of Thrones" costume for Purim

Material Girl, meet the Mother of Dragons.

Madonna dressed up as "Game of Thrones" heroine Daenerys Targaryen -- complete with a platinum blonde wig and fake dragons perched on her shoulders -- to celebrate the Jewish holiday of Purim.

The 55-year-old singer shared a photo of the costume on Instagram, writing, "Happy Purim!!!!! All Hail All Queens! ##certainty."

Purim is a holiday traditionally observed with carnival-like celebrations and costumes. Madonna was raised Roman Catholic but converted to the Judaism-based Kabbalah in the 1990s.

We'll take this ensemble to mean Madge is a "Game of Thrones" fan. The show, meanwhile, returns for its fourth season April 6 on HBO.
