All sorts of emotions were running around inside me
The 49 year-old explained that during her on-off relationship with Simon he was adamant that he didn’t want children - so news of Lauren Silverman’s pregnancy came as a shock.
Speaking of the moment the 53-year-old music mogul told her he was going to be a dad, she said: ‘I was completely and utterly stunned.
‘I was in such a daze, to the point where I wondered if I was dreaming it.
‘He sounded… odd, calm, strange, which threw me. I don’t mind admitting all sorts of emotions were running around inside me.
I didn’t realise he and Lauren were falling in love and, when I found out, I will admit I was taken aback and did feel a sense of betrayal
‘He was concerned about how I’d take it, which, on reflection, he didn’t need to be. He didn’t owe me that consideration.’
The singer admitted: ‘I suppose there has been a certain amount of comfort for me in my not having a child with Simon as he never wanted to have children.
‘That’s who he was, you accepted it. Then, to discover that he is going to have a child, only with someone else and they’re building this life together…
‘All those crazy things were going through my head and it’s not fair and it’s not pertinent to Simon and Lauren’s situation and I don’t have a right to feel that way. But I’m being honest.’
Sinitta met Simon as she began a pop career with him promoting her music and the pair first dated in the 1980s.
Although they have remained close since, Sinitta insisted she had no idea of the affair between him and Lauren - who was married to real estate boss Andrew Silverman.
She told a UK magazine: ‘We knew we were all close friends but I didn’t realise he and Lauren were falling in love and, when I found out, I will admit I was taken aback and did feel a sense of betrayal.’
