Natasha Stewart, aka Pebbelz Da Model, pleaded not guilty on Wednesday in court in Hinds County, Mississippi. The hip hop model is facing charges linked to the fatal injection of concrete into the buttocks of an Atlanta woman.

Pebbelz was arrested earlier this month, and is being charged with murder, conspiracy to commit murder, wire fraud and conspiracy to commit wire fraud.

The 39-year-old woman is facing charges of being an accessory in the murder of Karima Gordon of Atlanta, who was injected with cement instead of silicone when attempting to enhance her butt.

Stewart's attorney Kevin Camp argues that Pebbelz had "minimal" participation in the procedure and that it was carried out by another person, Tracey Lynn Garner, also known as Morris Garner.

Stewart is set to appear for trial on July 22, while Garner will appear on April 8.
