Britney Spears is being sued for $10m in a lawsuit relating to her perfume brand Radiance.
The singer has been accused of breach of contract, fraud and deceit, according to celebrity website RadarOnline.
The lawsuit, filed on Wednesday in Los Angeles County Superior Court, relates to her branding deal with beauty firm Elizabeth Arden, worth $15m a year.

Britney and her father Jamie are accused of being 'sneaky and underhand' by trying to cut Brand Sense PArtner, LLC. out of a licensing agreement.

In the court documents it is stated: 'Britney secretly made a separate deal with Elizabeth Arden in a sneaky underhanded effort to circumvent and evade its obligations to Brand Sense.
'Effectively, Britney improperly and illegally cut Brand Sense out of the Elizabeth Arden deal.'
Britney is being accused of 'concealment and evasive actions' by Brand Sense.
The suit adds that Brand Sense has a 'contractual right to 35 per cent commission on any Britney Spears-branded fragrance sold by Elizabeth Arden'.
It claims that Jamie Spears, who remains his daughter's conservator, 'complained that the commission was too high and said that Britney did not want to pay it'.
A compromise deal was reached where royalties were delivered directly to Britney.
But the details only emerged when Elizabeth Arden sent a letter to Britney and Brand sense, on February 16 this year, with a revised royalty report which did not include the Radiance scent.
Spears released Radiance, the ninth scent in her collection, in September, last year.
She also appeared in her comeback video Hold It Against Me holding a bottle of the perfume, which was released around the same time the alleged fraud came to light.
