Lauren Silverman wants Simon Cowell to stay away from Sinitta.
The US socialite who is expecting a son with Simon Cowell is angry the media moguls continued closeness to his ex-girlfriend.
A source quoted by the Sun on Sunday says: "Lauren doesn't want Simon near Sinitta anymore.
"And as difficult as it is for him, Simon is going to back the mother of his baby. Simon tore a strip off Sinitta - but then he pleaded with her to see sense and keep a low profile.
Sinitta though appears to be consumed with jealousy with the source adding, "But she's being driven insane with jealousy and isn't able to control herself."
The reports have come after Sinitta wrote on Twitter promising she would speak the truth about her abortion of Simon's baby a few years ago, and friends are said to be concerned she is heading for a breakdown.
Another report appears in the Daily Star Sunday paper, quoting an insider as saying: "This isn't the way Sinitta saw it happening in her head.
"The news had knocked her completely and she hasn't been in a good way since she found out. Simon always told her he didn't want children.
"She didn't think he would ever start a family and believed if he ever changed his mind, he would start a family with her. She is finding it hard to control her emotions and friends are worried about her, they think she is having a breakdown."
