The 'Pyramids' hitmaker's relative, Sha'Keir Duarte, who filed a lawsuit in August against the 'Fine China' singer claiming Chris' bodyguard violently beat him up when the two singers and their entourages got into an heated confrontation outside Westlake Recording Studio in Los Angeles in January, says he suffered a huge amount of physical and emotional pain as a result of the confrontation.
Sha'Keir has submitted an itemised list of what he is seeking damages for in new court documents, obtained by gossip website TMZ.com, that includes $1 million for pain, suffering and inconvenience, and $1 million for emotional distress.
He is also seeking $1 million for punitive damages and an additional $60,000 for medical expenses.
Chris, who is currently undergoing a court ordered 90-day stint at a live-in rehabilitation centre to focus on his anger issues, filed documents to counter-sue last month, in which the star, 24, claimed that Sha'Keir provoked the fight by threatening to kill him.
He also accused Sha'Keir of kicking and punching him, and insisted that he attempted to avoid the altercation ''with the aggressive and hostile Mr. Duarte.''
It was previously reported that Chris fled the scene straight after the fight, while Frank stayed to speak to police officers.
The 'Sweet Life' hitmaker, 25, took to Twitter shortly after the brawl to say he was ''jumped'' by Chris and his hand had been badly injured but he later decided not to press charges.
He explained his decision at the time, writing: ''I'll choose sanity. No criminal charges. No civil lawsuit. Forgiveness, albeit difficult, is wisdom. peace, albeit trite, is what I want in my short life. Peace.''
His new album Underneath It All is out now.
