Britney Spears is coughing up some dough to settle a lawsuit in which she’s accused of being a perfume traitor.

Britney was sued by Brand Sense Partners – a beauty company that hooked her up with Elizabeth Arden to front her Radiance perfume.  Under the deal, Brand Sense was supposed to get 35% of Brit’s profits.

But according to the suit, Britney and daddy Jamie entered into a secret deal with Elizabeth Arden and cut Brand Sense out of the deal.

The financial terms of the settlement are redacted, but the docs make it clear — Britney paid Brand Sense commissions for a period of years, in addition to a lump sum.
