Reeva and Oscar's love messages read in court.

Reeva Steenkamp and Oscar Pistorius exchanged loving text messages days before he allegedly murdered her, the North Gauteng High Court in Pretoria heard on Tuesday.

"Truth is, I miss you," read a message from Reeva on 29 January last year around 21:00.

"I'm missing you so, so much!" Oscar replied.

The messages were read to the court by Captain Francois Moller, who downloaded data from the couple's iPhones.

He was prompted to read them to the court by Advocate Barry Roux, for Oscar, during cross-examination.

Roux was making the argument that the couple were in a loving relationship, as "90%" of the messages exchanged between them in the weeks before Reeva's death indicated.

On 4 February, Reeva wrote to him: "If you want to go chill with him that's cool angel... I can come to you whenever."

Pistorius replied: "No baba, I want to chill with you."

On 11 February, she wrote: "I'm always on your side but mostly pro us and the health of our relationship."

Another message from her ended "I have said a small prayer for both of us”.

"Kiss, kiss, kiss," Roux added, reading from a written copy of the messages.

On Monday, Moller, being questioned by prosecutor Gerrie Nel, read to the court messages from Reeva to the athlete portraying a possessive Oscar who threw temper tantrums.

He has been charged with the premeditated murder of Reeva and of contravening the Firearms Control Act and has pleaded not guilty to all the charges.
