Rita Ora is reportedly suing a merchandising company over image rights.

The 'How We Do' hitmaker claims she was exploited by Scottish firm GL Dameck Ltd, which specialises in clothing lines, and she's planning to sue them for more than £100,000, according to The Sun newspaper.

Court documents reportedly show Rita is looking to win £108,000 from the firm, who she says owe her from an agreement in November 2012.

The sum is said to be based on an initial demand of £90,000 which when VAT, costs and interests have been added on, totals over £100,000 and she also wants an injunction to stop the company from selling goods linked to her.

The 23-year-old star was signed as the face of GL Dameck label Superga last year and the range was sold through the subsidiary Milanclothing.com but the goods she fronted no longer feature on either of the firm's websites.

Rita - who has been dating surperstar DJ Calvin Harris on and off for over a year - recently revealed she had turned down the opportunity to be a judge on the UK version of 'The X Factor' because she wanted to focus on her own career.

She said: ''I have so much to accomplish first and it's kind of a full-time job being on X Factor. It's not like a nine to five. It's constant, for months.''
