Selena Gomez is counter-suing a fragrance company, which is accusing her of backing out of a multi-million dollar endorsement deal.

The 'Come And Get It' singer - who recently rekindled her relationship with on/off boyfriend Justin Bieber - claims perfume makers Adrenalina actually owe her at least 5.2 million because their business deal fell apart.

A source told gossip website TMZ.com that Selena has filed a countersuit against the company claiming she only backed out because Adrenalina was going broke and couldn't afford to manufacture or market her perfume line.

The company filed a lawsuit against the 20-year-old brunette beauty last month for breaking a contract to be a spokesperson for the brand.

According to court documents filed by her attorney Michael Weinsten, Adrenalina promised to pay the 'Spring Breakers' star 5% royalty on sales of all Selena-brand scents, and guaranteed her minimum earnings of $5.2 million.

Her legal team insists Selena only terminated her contract with the company to protect her reputation after she discovered it could barely afford to pay its own employees.

Mr Weinsten previously said their lawsuit was without merit, adding: ''Any claim that Selena did not meet her promotional obligations is ridiculous, manufactured after Adrenalina was terminated. Selena will vigorously defend this lawsuit, and will soon bring her own lawsuit against Adrenalina for millions in damages.''
