Julia Carta chats to The Daily Star about working with Simon and how his baby news shocked everyone close to him.
Despite being his make-up artist and close confidante for 12 years, Julia has always refused offers to join the gaggle of girlfriends on his famous yacht.
Now, as Simon’s surprise baby news rocks his showbiz clique, Julia lifts the lid on his hectic world of parties, holidays and top telly shows.
She says: “I keep getting invited on his yacht, but I turn it down. I have a boyfriend – I don’t want to get involved with all that. It’s not my cup of tea.”
But 38-year-old Julia is certainly close to Simon, which is hardly a surprise.
And she has more than a passing resemblance to his ex-girlfriends Mezghan Hussainy, 40 (also his make-up artist), Terri Seymour, 38, and Jackie St Clair, 52.
“I don’t know why he always surrounds himself with brunettes,” Julia says with a wry smile. “He definitely has a type. But that’s a question for him, not me.”
Simon famously holidays with his harem – which also includes Sinitta, 49 – on the £40m Slipstream boat every year. It’s where the 53-year-old is said to have first hooked up behind her husband’s back with Lauren Silverman, soon to be the mother of his baby.
Julia says: “I won’t travel with Simon because I don’t want to be one of the harem. I’m not part of the harem. People might say I am, but I am not. I’m much happier behind the camera than in front of it.”
Julia confirms that the pregnancy wasn’t exactly planned.
“Everyone was shocked to hear Simon was going to be a dad,” she says. “None of us expected it to happen. Even Simon didn’t ever expect it to happen.”
Although they have no plans to wed, Simon has vowed to stick by Lauren, 36, and the pair have recently been cosying up together in the South of France.
“He introduced me to Lauren earlier this week when they were in London,” Julia reveals. “She was very sweet and excited. I thought she was nice.”
And of the number one woman in the supremo’s life, his mother Julie, she beams: “Simon’s mum is amazing. She’s absolutely thrilled. She’s ridiculously excited because she never thought it would happen for Simon. But it has and I hope everyone is happy for him.”
Julia works her magic on Simon during Britain’s Got Talent this year.
We’re gossiping at a top London hotel where Julia is giving me a makeover using the new range from Sheer Cover make-up, a brand she swears by for her A-list client.
“I love being a make-up artist – people confide everything to you,” she tells me as she dusts over some of the new range’s mineral powder.
She is confident about her position, and says there is no rivalry with Mezghan.
“She is his US make-up artist and America is her domain,” says Julia. “I’m his make-up artist when he’s here in the UK. But there’s no rivalry. I turned down going to the US with him.”
Despite recent reports that Simon didn’t want to change nappies and speculation he didn’t want to be a hands-on dad, Julia believes he will love being a father.
“He’ll be an amazing dad,” she says. “Of course he’s going to have to learn to change nappies. Welcome to the real world, Simon! That’s a big part of it for him now. Men have to change nappies, though – he will. You learn fast and become immune to the smell.
“I will be stocking up concealer for him in case he has lots of late sleepless nights
“He loves kids and he is very good with children. He will thoroughly enjoy the challenge of being a dad. He’ll make an brilliant father.”
Julia, who works with the star on all of his big TV projects including X Factor and Britain’s Got Talent, says that behind the scenes, Simon is a delight.
“He’s so easy to be around,” she says. “In the make-up chair he just likes a bit of primer, concealer, powder and lots of bronzer. Oh, he likes to be tanned.
“Simon’s old-fashioned and wouldn’t wear guy liner or mascara or anything. He has lovely long natural eyelashes anyway.
“He takes his skin-care regime seriously and likes to look fresh and radiant. Simon loves a bath. He spends hours in there and I’m always chucking new products at him to try.
“Simon’s made the show such a phenomenon and I can’t believe it’s in his 10th year and how things have changed.
“I’m so proud of what I do. Simon’s always been very good to me.”
