But Paula Abdul is not one of them.
The singer kept mum as she stepped out in Beverly Hills on Thursday after the rumours emerged.
Low profile: Paula Abdul stepped out on Thursday amid claims her pal Simon Cowell is fathering a child
The 51-year-old is one of the music mogul’s close pals and appeared alongside him on the judging panel for eight seasons on American Idol and one season on X Factor.
Paula kept a low profile as she left a hair salon and hopped into her car alongside her assistant, covering her make-up free face with large round sunglasses.
It is not known if Paula has spoken to Simon in the wake of the news, or if she can confirm it is true, but the star was wearing something of a knowing smile.

The Opposites Attract hit-maker was dressed comfortably in a sheer blue cover-up over a black tank top.
She also gave her 5ft stature a boost by sporting a pair of black platform heels which were hidden under the legs of her bellbottom jeans.
While Paula was treating herself to a pamper session at the hair salon, Simon was attending an X Factor press panel.

And the 53-year-old, who is said to be fathering a child with socialite Lauren Silverman, deflected all questions about the rumours.
'Unfortunately, I have to keep this private for the moment. It's just one of those things, but thank you anyway,' Simon said at the Fox panel at the Television Critics Association meeting in Beverly Hills.
And when a reporter asked, 'The new baby. Were you as surprised by the news as we were?' the British born reality TV mogul replied, 'I haven't read the newspapers. Am I missing something?'

He added: 'There are a lot of things I will eventually clear up when the time is right. I really have to be sensitive here because there are a lot of people's feelings involved.'
When asked if he could reveal how he's feeling, Simon candidly replied, 'I would love to, but I have to respect a lot of other people's feelings.'

After the news broke on Wednesday that 36-year-old Lauren is expecting Simon, who is worth an estimated $305 million, insisted he will do everything he can to support and provide for his child, according to reports.
It has now emerged that Mrs Silverman’s husband, Andrew, has cited Cowell in divorce papers, in a move which could potentially force him to reveal details of the alleged affair in court.
Lauren, who has a seven-year-old child with Andrew is accused in the recently filed papers of adultery with Cowell and of being ‘cruel and inhuman’ towards her husband.
