The singer has admitted she "wasn't well in the head" when she was taken off the US version of the show just weeks into the job.
McFly star Tom Fletcher has beaten Simon Cowell to win Celebrity Dad of the Year following many doting social media posts about his son.
Acts from across the globe compete in tonight's new series, but Simon Cowell says we'll see once more that Britain really does have talent.
Simon Cowell says he was "born to be a dad" and has hinted that he may have more children so that his son Eric, who was born on Valentine's Day, can have a brother or sister.
The 54-year-old X-Factor judge told Extra: "I wouldn't rule out (more children). Well, I got (Yorkshire terriers) Squiddly and Diddly, and I couldn't imagine Squiddly or just Diddly... I had a brother when I was younger, so I kind of think it's cool to have two or three ... two."
Cowell, who was interviewed by his ex-girlfriend Terri Seymour for the magazine, revealed that he cried at his son's birth after dashing to New York from London - where he was filming Britain's Got Talent auditions - to be at girlfriend Lauren Silverman's side.
He admitted he was so apprehensive about becoming a father that he asked his partner, "'What if I like the dogs more than him?', because I've never had a baby before, and she said, 'You're gonna be absolutely fine', and then literally within seconds of him being born, I got it."
The first public preview of The X Factor musical I Can't Sing! will go ahead tonight after it was postponed twice in one week:
Hello. Am very excited and relieved to confirm the first public preview for #ICantSingUk the X Factor musical is tonight.
It's difficult to describe because I have never seen anything like it before. I hope you love it as much as I do.

Record producer Ian Levine has told how he smashed a record over Simon Cowell's head in a packed nightclub after he tried to force him to play a Sinitta record.
Levine was DJ-ing at gay club Heaven as Cowell was trying to make his then protege Sinitta a star with her single So Macho.
But in an interview to be screened in Channel 4 documentary Queer As Pop: From Gay Scene To Mainstream, Levine said he was angered that the music mogul was trying to cash-in on the gay market.
He said of the track: "It was a step too far... cynically designed to get the gay record sales."
Levine, who was the resident DJ at the London gay club at the time in the mid-1980s, said: "Simon brought Sinitta to the DJ booth at Heaven, because I banned the record. I told him I am not playing this... no way - I am not playing So Macho."
X Factor boss Simon Cowell has not spoken to this year's winner, Sam Bailey, but the singer said she hopes they meet up soon.

"I've not spoken to him directly but he's very busy as I am but we'll meet each other soon".After her win, Cowell tweeted to say "congratulations" and described her win as "well deserved".
