Simon, 53, is rumoured to be fathering a child with Lauren but has yet to confirm these claims.
He remained tight lipped on the subject when quizzed during a press conference for the Television Critics Association yesterday (1 August) and instead joked that he "hadn't read the papers".
However, Carmen - who is thought to have briefly dated Simon last year - appears to be already imagining the music mogul as a doting dad and believes that he will take good care of his child, should the reports be true.
Speaking to Us Weekly, the actress and model said: "I obviously think that his child will be very well taken care of and very, very loved."
Carmen seemed to be pretty excited about the prospect of The X Factor judge becoming a parent - if it's true - and admitted that she is eager to know whether it would be a boy or a girl.
Meanwhile, one of Simon's other former flames has also reacted to the baby rumours.
On Monday, 80s pop star Sinitta tweeted a cryptic message that many have suggested could be regarding the recent baby rumours.
She wrote: "Something has just happened...half miracle, half nightmare! #WakeMeUpIWantToGetOff."
Reveal have contacted Simon's rep for comment on the baby claims.
