Oscar Pistorius not only cried but also forced himself to vomit to elicit sympathy, the mother of his slain girlfriend says.

June Steenkamp told NBC News that she believes Pistorius' actions and reaction in the courtroom to photographs of Reeva Steenkamp after she shot her four times in the a bathroom door in their home during his murder case that caused him to get sick in the courtroom were insincere.

Outcry over Oscar Pistorius sentence muted because a black, female judge handed down the sentence?

"The vomiting and the crying? That was all for himself. That was for him, because he's done something wrong, he's in big trouble. Me, myself and I, that's it," she told NBC News, but insisted that she "wouldn't want to hurt" Pistorius in any way because she is not out for revenge.

June Steenkamp added that she wanted only the truth to come out as to what happened on her daughter's fateful night on Valentine's Day morning, 2013.

Oscar Pistorius' lawyer denied reports that Pistorius was enraged by the appeal that the prosecution was granted

"Oscar knows the truth, Reeva knows the truth but she's not here anymore. Something terrible happened that night," she said. "I just want the truth and to be fair, but it's not going to change my life ... I'm moving on now."

Last week, June Steenkamp told the Belfast Telegraph that she still wants to meet Pistorius in prison because she does not believe his version of what happened in the early morning hours when he shot her.

"I don't quite know what I'm going to say but I think it's only fair that he has to face Barry and I, because he's taken a life away from us," June said to the Belfast Telegram. He has to have that in his face - we won't have her grandchildren, or her wedding. He's taken so much. He's robbed us of our lives."

Reeva's mother tweaked her wishes a bit for her NBC interview:

"I'm not really worried what happens to him... every night he's going to see Reeva's face, so he's already being punished quite a lot," she explained to NBC News. "If they give him another 20 years, it's not going to make a difference to my life... When they took him down those steps and they took him to jail and they took away his cell phones and his luxurious life and his spoiled life ... it didn't matter for how long."
