The 'So Macho' singer made her confession in the wake of the news Simon, 53, and his girlfriend Lauren Silverman are expecting a child together in response to a report that came out about the termination which was false.
Sinitta insists the music mogul never had a problem with her and understood why she felt the need to speak out.
During an appearance on TV show 'Lorraine', she said: ''Simon and I were always OK. In fact like a lot of adversity sometimes it brings you closer because I think as much as it was difficult.''
Before she set the record straight, Sinitta posted a series of emotional outbursts about the abortion on her Twitter account, something she admits she did in anger.
She explained: ''I'm still sane. I got very angry and I'm normally the sort of person that lets things wash over me. It was a very sensitive topic and also I felt that it was being reported in the wrong way. And it was being used to look like I was trying to attack Simon with it, who is my best friend.
''I thought, 'I can't just think it's fish and chip paper tomorrow.' ''
