Oscar Pistorius pleaded not guilty at the start of his murder trial in South Africa.
As he entered the courtroom, he walked past the mother of the woman he shot and killed a year ago.
The double-amputee Olympic athlete arrived in the courtroom at the high court in Pretoria wearing a dark grey suit and black tie.
He sat and drank from a bottle of water.
Pistorius is charged with murder with premeditation in the shooting death of girlfriend Reeva Steenkamp in the pre-dawn hours of Valentine's Day last year.
Pistorius says he shot Steenkamp by accident, thinking she was an intruder inside his bathroom.
Steenkamp's mother, June, earlier entered the court dressed in black.
