X Factor boss Simon and his girlfriend Lauren Silverman welcomed their first child in February and Sinitta said becoming a father has changed him for the better.
The 80s pop star told Phillip Schofield and Holly Willoughby: "He has - I won't say mellowed - because he is still naughty and crazy, but he's just very open, very tender."
"Lauren has said that he wants more children, he wants a little girl next."
Sinitta returned to the This Morning sofa on Thursday, after speaking in September last year about the "betrayal" she felt when she was told Simon was set to become a father.
She claims that when the pair were in a relationship in the 1980s he had told her he did not want to have any children.
But she now insists they remain good friends, saying: "We have all survived and we are all happy, Eric is adorable. I'm godmother to Eric so that was lovely.
"Like all good friendships we have weathered the storm and kept going."
In the 80s, the singer notched up nine UK Top 40 hits including So Macho and Toy Boy, and after nearly 20 years away from the recording studio she is back with a new single.
The track, So Many Men, So Little Time, was a hit for her mother Miquel Brown back in the early 80s.
Sinitta has high hopes for her return to the music scene, but admitted she hasn't heard any feedback from Simon.
"He was send it yesterday," she said. "I'm not sure if it's a good thing or a bad thing, maybe because it is too early in the morning for him, (but) I haven't heard (back) yet.
"I told him to just say what (he) thinks, but it's done now so it won't change anything whether he likes it or hates it."
