Circus Fantasy is a fragrance created by Britney Spears and Elizabeth Arden.
The bottle is the same as the previous Fantasy fragrances except that the bottle is a light blue with red crystals.
This is the first fragrance that Elizabeth Arden created specifically for an artist's album.
A gift set includes Eau De Parfum Spray 50ml, Body Souffle 100ml and Lip Gloss 8ml.
The fragrance contains: raspberry, apricot blossom, peony, lotus, orchid, vanilla, musk and candy.
In Australia, a promotion deal was set up with Myer. For a limited time, customers who bought a 100 ml bottle would also receive a free CD featuring a remix of the song "Circus" and the song "Kill the Lights" (taken from the "Circus" album).
It was shown in the music video for "3".
