Simon Cowell has looked after his son on his own for the first time.
The media mogul - whose girlfriend Lauren Silverman gave birth to Eric in February - was "left alone" with his baby when she visited family in New York, and it is said he coped "really well".
A source told the Sunday Mirror newspaper: "Simon was a bit nervous about being left alone with Eric at first but in reality he has nannies to help, so it's not been too bad.
"He's actually risen to the challenge very well. When Eric has a tantrum he finds it very amusing - it sort of reminds him of being in the ['Britain's Got Talent'] judging panel."
Simon is a first-time father but he's settling into his new role despite having "never even held a baby before".
His friend and former girlfriend Terri Seymour recently said: "He's great actually. I mean he hasn't changed his lifestyle because Simon wouldn't.
"But he's very good. He'd never even held a baby before, so he was like, 'How do you hold a baby?'
"You have to remind him every now and then about the head... But he's really good and he loves it."

One Direction are considering suing a condom brand for selling a range based on the group.
The US company has brought out the unofficial merchandise - which has the cheeky name 'One Erection - Up All Night' - and while the 'Story of My Life' hitmakers saw the funny side their management was less impressed.
An insider told the Daily Star Sunday newspaper: "The boys heard about the condoms and found them hilarious. They even joked about buying a few packets for a laugh.
"But their management team aren't seeing the funny side. They are considering bringing in lawyers to stop them shamefully exploiting the band to sell condoms.
"It's only a small US online firm so management weren't too concerned at first but they are still worried the range damages the group's image."
It is also reported that the band have rejected various offers from bigger brands to release their own range.
The source added: "What makes it worse is 1D have turned down various big-bucks offers to bring out their own official range.
"So they aren't happy someone else is cashing in on their sex symbol status."

Mollie King loves The Saturdays too much to try a solo career.
The blonde beauty has insisted she won't quit the girl group because she would miss having her band mates there to share every experience with.
She told the Sunday Express magazine: "I think I would have the guts to go it alone.
"But I just love doing it with the girls because, as much as you can call your mum when you get off stage, you can never explain the exact feeling.
"With the girls when you come off, you're all like, 'My God! Did you see that?' And that's something you'll never get if you're up there on your own."
Her dedication to the band even means Mollie is having to try to balance her career with a long-distance relationship.
She is living in the UK, while her boyfriend Jordan Omley is a producer in Los Angeles.
She explained: "We travel a lot to meet up but obviously we don't see each other every day.
"I live on Skype and FaceTime ... I do love it out there. It's such a nice lifestyle, isn't it?
"I love the people and the weather but my career is everything to me right now - and that's here."

Michelle Collins is in talks to compete on 'Strictly Come Dancing'.
The former 'Coronation Street' actress could see her name value boost just in time for new casting opportunities and would give her a chance to spend more time with her daughter Maia in London.
An insider told The Sun on Sunday newspaper: "Michelle has said before that the show appeals to her - and the timing would be perfect as there is always a casting rush in January.
"'Strictly' would raise her profile just as that rush begins ... For Michelle, 'Strictly' also has the bonus that it is London-based. She left 'Corrie' because she wanted to be in London with her daughter, Maia.
"So the last thing she would want is another job that would take her away again. 'Strictly' would guarantee her three months in London."
Michelle has admitted in the past she would be happy to compete on the ballroom dancing show, even if her "competitive" streak led to a clash with the judges.
She said: "Never say never - out of all of [the reality shows] I'd do 'Strictly'. But I'm quite competitive and I don't like to fail at anything.
"I'm not a very good dancer and I wouldn't take being criticised by Craig Revel Horwood very well. I would probably end up punching him."

Charlotte Crosby learnt a lot about relationships during her new reality show.
The star - who recently filmed her own programme 'The Charlotte Crosby Experience' in four different communities across the world - admitted she was taught important life lessons about love.
She told the Sunday People newspaper's Sunday magazine: "I'm the type of person who, when I'm arguing with my boyfriend I think, that's it I'm finishing with him.
"But finishing with someone or getting a divorce is just not a question for the people I stayed with in India or Canada ... You look at all the great times you've had together and you don't just focus on the one bad time."
The 'Geordie Shore' star has made sure to bring her new attitude home with her and used it to solve arguments with her boyfriend Mitch Jenkins.
She said: "I had an argument with my boyfriend after the show, and I just said, 'Look, we'll speak when we speak, I need a couple of days to forget about it'.
"Normally I'll be on Facebook 'unfriending' him, but I haven't done that once in our whole relationship.
"But believe me there've been times where I've wanted to. I did delete all his photos off Instagram once but that was before I learned the life lesson."

Jason Sudeikis reportedly fainted while Olivia Wilde was giving birth.
The 38-year-old actor was determined to support his fiancée throughout her entire labour with their first son, Otis, in April but at one stage he passed out in the delivering room.
A source told National Enquirer magazine: "Jason was in the delivery room for Olivia, but witnessing and assisting in the birth suddenly became too overwhelming when he took one look at his child starting to be born, turned pale, mumbled something to a nurse and then went down for the count."
The 'We're The Millers' star was worried he had missed his son's arrival after regaining conscious, but was assured by two nurses that he hadn't and then stepped back into the fray to support Olivia, 30.
The source added: "Jason was totally fine from that moment on, endlessly tending to exhausted-but-ecstatic new momma Olivia and their bouncing baby boy."
The proud mother and father have been enjoying every aspect of parenthood so far, and have already enjoyed some hilarious moments with baby Otis.
'Drinking Buddies' star Olivia recently revealed that Otis peed on his own face whilst she was changing his diaper.
She wrote on Twitter: "Having an infant son alerts me to the fact that every man, at one point, has peed on his own face. #awesome (sic)"

Katie Price is pregnant with her fifth child.
The former glamour model only just found out she has been expecting for six months, with her latest pregnancy beginning in November just 12 weeks after she gave birth to her son Jett in August 2013.
An insider told The Sun on Sunday newspaper: "It's not something they had planned this soon after Jett, but they're still delighted. The news came as a complete shock.
"Katie's already in her second trimester so has been pregnant for nearly six months without even realising. She's due later this summer.
"Unlike her other four pregnancies she's yet to have any cravings and is not showing much, either."
The baby will be her second with husband Kieran Hayler and it is said she wants many more to grow their family.
The source added: "Katie's always wanted a big family and a fifth baby's just another part of that. Kieran wants the same thing too.
"Katie's 35 now, so it's no surprise she has fallen pregnant so quickly after Jett. She wants eight children in total, so this pregnancy is definitely a step in the right direction."

Gary Barlow surprised a fan on her wedding day by serenading her.
The Take That star turned up at Louise Newman's special celebrations to mark her big day with a rendition of 'A Million Love Songs' and a card offering his congratulations.
Speaking to the Sunday Mirror newspaper, she said: "I heard the opening bars to 'A Million Love Songs' and was swaying and swinging along when someone called my name.
"I looked round and there was Gary. It was just magical. I went up and cupped his face in my hands, then he got down on one knee and sang to me.
"He even brought me a card saying 'To Lou, many congratulations on your special day, Gary B' with six kisses!"
The surprise was planned between Gary - who also performed his hit 'Relight My Fire' - and maid of honour Emily Alcorn following a year-long Twitter campaign to get him to attend the emotional ceremony.
Louise added: "I've been a massive Take That fan since I was six. The campaign started as a bit of a joke, but for the last few months I thought Emily had gone off the idea, so I gave up hope.
"Now I know Gary was plotting with her all along ... [my husband Mark Francis] was thrilled.
"He's never shared my passion for Take That - but he loves Gary as much as me now."

Pixie Geldof has been "working hard" to cope with her sister Peaches' death.
The singer and model is mourning the loss of her sibling and it is said she has "thrown herself into" a solo career as major record labels begin to bid for her talents.
Speaking to The Sun on Sunday newspaper, a source said: "Pixie's thrown herself into her work to get over the death of Peaches.
"She's working hard to keep her head down in the zone and staying focused.
"In fact, she sees it as a tribute to Peaches, who was so into music, that what happened will inspire tracks for her debut."
Meanwhile, friends were reportedly concerned after Peaches - whose death was "likely" linked to heroin use - admitted she was worried she "could easily relapse" into drug addiction.
A friend revealed: "Every day was a challenge for Peaches. It's the same with anybody with an addiction.
"We'd talk about it on Skype, or on Viber, and she would confess from time to time that she could easily relapse.
"She didn't want to, of course, but sometimes she would become overwhelmed by an incredible urge. She was still haunted by her mother's death and that was something that still caused her pain every day."

Aloe Blacc doesn't believe you have really made it in the music business until you've recorded four albums.
The 35-year-old singer insists longevity is the key to being a respected musician but he is worried new artists aren't going to get the chance to develop over several records.
Blacc said: "I don't think you've made it in the music industry unless you've got four solid albums and maybe three bona fide hit songs from each album. That's making it in the music industry, and not many artists are going to have that chance ever again because of the metabolism of the music industry right now. It's so quick and that's just the way that the marketplace works. I'll be lucky if I get a second hit."
Aloe worked with Pharrell Williams on his track 'Love is the Answer', which features on his new album 'Lift Your Spirit', and he admits he was pleased to be able to give the producer a chance to be involved in something less controversial than Robin Thicke's 'Blurred Lines'.
He told BANG Showbiz: "I was happy to work with Pharrell to then give a chance for Pharrell's production to stand for something positive. At the time he told me he was working on 'Happy' so I was really excited to know that he was working on the same thing. To create music that was going to open people up to positivity."

Arnold Schwarzenegger has been injured on every action movie he has starred in.
The 66-year-old actor has been hurt throughout his film career, with many mishaps resulting in him ending up in the emergency room, but none of his injuries have resulted in a set being "shut down".
He explained:"[Producers] don't like you to get injured, I get injured in every movie, but its small things like banging you're head on the camera - and you just go and get stitched up quickly in the emergency room and then you come right back and continue shooting - but when you injure your leg or shoulder that's when things shut down."
Schwarzenegger - who can currently be seen in crime thriller 'Sabotage' - has always been in top physical condition throughout his career and first made a name for himself as a champion bodybuilder.
However, he admits there are "certain exercises" he can no longer do because at his age he could easily get injured.
Revealing his best workout tips, Schwarzenegger told BANG Showbiz: "If you are going to work out you should really do the whole body. You should go from one machine to the next, don't stop, and adjust the weight of the machines to prevent injuries. As soon as you get older you get injuries, there's certain exercises you can't do."

Hugh Jackman was scared of the dark as a child.
The 'Prisoners' actor has admitted that when he first became a parent to his adopted children, 14-year-old Oscar and eight-year-old Ava, with his wife Deborra-Lee Furness he didn't have any idea how to be a father and thinks it's because he was an anxious child who had various fears.
He said: "I was surprised how little my own parenting instincts kicked in. I was a bit of a pain in the arse at first, insisting he couldn't have a bottle straight before bed because I'd read up on it.
"My own mother finally said, 'Look, you may have read a lot of books, but the kid [Oscar] hasn't, so put them down.' But I was quite a fearful kid myself. Heights, the dark..."
The 45-year-old Hollywood star admits he even incorporated a fear into his 'X-Men' character Wolverine because he didn't want to play someone who isn't capable of feeling scared.
He said: "I put a fear of flying into Wolverine that wasn't in the script. I thought, 'I can't like somebody who isn't scared of anything.'"
