Oscar Pistorius was asked to read out the Valentine's Day card form the model, 29, which read: 'Roses are red, violets are blue. I think today is a good day to tell you that…I love you.'
Reeva had also wrapped a picture frame containing snaps of the couple in loving poses, on the beach, and at a Christmas party.
However, Oscar never opened the present or card on the night, and they remained unopened for many months after the incident in which Ms Steenkamp tragically lost her life.

Gerrie Nel for the prosecution has accused Pistorius of 'tailoring' his evidence as the trial goes on, constantly inventing a new version.
Finishing his cross-examination, he said: 'We should blame somebody…Should we blame Reeva? Should we blame the government?'
'You fired four shots through the door whilst knowing that she was standing behind the door' said Mr Nel.
He finished with: 'She was locked into the bathroom and you armed yourself with the sole purpose of shooting and killing her.'
Pistorius faces 25 years in prison if he is convicted of premeditated murder.
