Blu Cantrell - Cantrell's Boyfriend Could Lose Sight After Fight

BLU CANTRELL's boyfriend TONY DE NIRO is fighting for his sight after he was glassed in the face at one of the R+B singer's gigs.

The BREATHE beauty was performing a secret concert at Paris club MILLIADAIRE when Tony was hit in the face with a glass ashtray, and the injury could cost him an eye.

The disagreement began after club bosses refused Tony's request to pay Blu in full because she only played two songs.

A vicious brawl erupted as the singer's party tried to leave at 3am, after which Tony was rushed to hospital in an ambulance.

The producer is expected to remain in hospital for the next few days.

An onlooker says, "The first thing we knew about the fight was when they came flying out of the door and into the street.

"There was a lot of kicking and punching and bouncers were trying to split it up.

"One of the men was lying on the floor covered in blood. He looked in a bad way.

"The police arrived and arrested a man, while an ambulance took the other one away. It was terrifying to watch."

Blu's spokesman says, "This was a terrifying incident and totally unprovoked.

"Blu will remain in Paris until Tony is discharged from hospital. She has been sleeping by his bedside and is very shaken by the whole thing.

"There was an injury to Tony's eye but it's too early to tell how serious it is."
