Kim Kardashian is hoping to get pregnant again before the end of the year.
The reality TV star is set to marry Kanye West in France this spring and then they are rumoured to be trying for a brother or sister for nine-month-old North.
A source told Yahoo! Celebrity: "She wants to start trying by the end of the year - even though she hated being pregnant.
"She's so besotted with North that she says she's totally forgotten the awfulness of being pregnant and how much she struggled."
The 33-year-old - who has sisters Khloe and Kourtney, brother Rob and half sisters Kendall and Kylie - is said to be keen for her daughter to have a sibling close to her in age.
The insider added: "Kim has such a big family that she feels it's really important there isn't a huge age gap between North and her siblings.
"She's got her body back and loves being slim and voluptuous, but she's going to relish it for a few more months and then try for another child after the wedding, even on honeymoon.
"Kim says it'll be the most romantic thing ever and that's what they've been talking about a lot."
Kim and Kanye's wedding is set to be a star studded affair, with a guest list thought to include chat show legend Oprah Winfrey, TV host Ryan Seacrest - who produces Kim's reality show, 'Keeping Up with the Kardashians' - actor Will Smith and his wife Jada Pinkett Smith, as well as close friends Beyonce and Jay Z.
The wedding will be filmed for 'Keeping Up With the Kardashians', although Beyonce reportedly doesn't want to feature on the programme.
The wedding will be Kanye's first and Kim's third marriage, after she tied the knot when she was 20 to music producer Damon Thomas for four years and later married basketball player Kris Humphries, in 2011, a union which lasted just 72 days.

Zac Efron's friends are "worried sick" he has fallen off the wagon.
The 'High School Musical' actor ran into trouble in an area of downtown Los Angeles notorious for being awash with drug dealers and dangerous at night on Sunday (23.03.14), and pals claim they don't believe he had driven there in search of sushi - as he told police - and fear he is back on drugs.
Zac admitted last year he had undergone two spells in rehab, and although he didn't disclose what he was treated for, it has widely been rumoured he had problems with cocaine.
A source told TMZ.com: "Zac's a loner. He goes out rarely and the idea of him driving for miles to go to some sushi restaurant in downtown L.A. after midnight is preposterous."
Zac, 26, had been accompanied by a man he called his bodyguard during the incident, which he told police had taken place when he had run out of gas on his way to a restaurant. He claimed as they were sitting in their car and waiting for a tow truck, he threw a bottle out of the window and it smashed on the pavement near the alleged attackers. He said three men confronted them because they believed the bottle had been deliberately thrown at them. Two men attacked the bodyguard, then Zac got hit on the mouth when he tried to help.
However, sources say Zac's friend - who has requested to remain anonymous - isn't a bodyguard at all, but a convicted drug dealer who has been hanging around the star a lot recently.
Zac also suffered a broken jaw last year when he claimed to have slipped on a fountain in his house.

Christina Aguilera is expecting a girl.
The 'Fighter' singer and her fiance, Matthew Rutler, are having a daughter according to JustJared.com, which will be their first child together.
The girl will be a sibling to Max, Christina's six-year-old son with ex-husband Jordan Bratman.
The singer is currently in Malaysia, where she performed for fans tonight (28.03.14), writing on twitter following the show: "Ain't no other fans... Thank you Malaysia for all the love & support! XoXtina (sic)"
Christina, 33, announced she was expecting in February, a week after Matthew had proposed and is said to be over the moon with the pregnancy, with one source saying: "It wasn't expected, but it also wasn't unwelcome. They are all very excited though! Christina loves being a mom."
Production assistant Matthew met the blonde beauty on the set of movie 'Burlesque' in 2010 while she was going through her divorce, and had been planning to propose long before Christina got pregnant, even starting to design her engagement ring more than a year ago.
He popped the question in the backyard of their new home in Los Angeles, which is still under construction, on Valentine's Day.
Christina was said to be completely "shocked" by Matthew's romantic sunset proposal, for which he wore a suit and filled a gazebo with candles and red roses, before taking her to celebrate with friends and family.

Matthew McConaughey's hat from 'Dallas Buyer's Club' has fetched $13,000 at auction.
The white cowboy hat worn by the hunky star for his Oscar winning performance as AIDS patient Ron Woodroof in the drama movie reached three times its starting bid price of $3,000 when it was sold by auction house Nate D. Sanders in Los Angeles.
The hat is a size 7 and 3/8 with a 4-inch brim and made in Texas. The headwear was also sold with a certificate of authenticity from Universal Pictures.
The hat is signed under the brim, where Matthew wrote in black marker pen: "Just Keep Living, Matthew McConaughey.''
Matthew's words are a reference to lines said by his character David Wooderson in 1993's 'Dazed and Confused', his first role, where he said: "Let me tell you this, the older you do get the more rules they're gonna try to get you to follow. You just gotta keep livin' man, L-I-V-I-N'."
Matthew and his wife, Camila, have also established a foundation called J.K. Livin, which is set up to benefit high school students.
Collecting his Oscar for 'Dallas Buyer's Club', Matthew thanked his family, including his mother, Mary, his late father, James, his wife, and their three children, Levi, five, Vida, four and Livingston, 14 months.
He also said: "I want to thank God, because he's the one I look up to, he's graced my life with opportunities which I know are not of my hand or any other human hand.
"He has shown me that it's a scientific fact that gratitude reciprocates. In the words of the late [British actor] Charlie Laughton, who said, 'When you got God you got a friend and that friend is you.' "

Olivia Colman is "too scared" to recycle her 'Broadchurch' scripts.
The 40-year-old actress claims the writers of the popular crime drama are so secretive with the plot that she won't put her script in the bin over fear it could be found.
Speaking at Broadcast Press Guild Awards (BPG), sponsored by the Discovery Channel, Olivia said: "I do [take care with the scripts], most scripts have watermarked copies, and i'm too scared to put them in the recycling."
Olivia - who revealed series two is scheduled to begin shooting in May - also said the cast agree to strict legal measures to prevent story lines from leaking.
She added: "It really is [an MI5 operation] you have to sign a legal document so it's all slightly scary."

Burger King have offered to cater Kim Kardashian and Kanye West's wedding.
The fast food chain have denied earlier claims the rapper was buying his fiancée 10 of their restaurant's branches across Europe as a wedding present, but have instead offered to rustle up some classic burgers and fries for guests at the showbiz couple's marriage reception.
A spokesperson for the company told NME.com: "Burger King Corp. is familiar with the recent news stories regarding Kanye West and Kim Kardashian.
"We are unaware of any purchase of Burger King restaurants made by either Mr. West or Ms. Kardashian, but we're available to cater the wedding!"
Kim, 33, and Kanye, 36 - who have nine-month-old daughter North together - are expected to tie a knot in a romantic ceremony in Paris this May in front of their family and friends.
The 'Bound 2' hitmaker was recently claimed to have decided to but his fiancee the restaurants to help Kim carve out a career as a businesswoman and step aside from her family's reality show, 'Keeping Up With the Kardashians'.
A source previously claimed: "As always, Kanye is thinking outside the box when it comes to gifts for Kim. She owns all the jewels anyone could ever want, so he is taking the practical route by investing in businesses for her instead.
"He knows the fast food industry is reliable and lucrative, plus BK is international so he thinks it's the perfect fit for Kim. Kanye wants to buy her 10 restaurants across the UK, Italy and France, making her a real international businesswoman."

Nick Cannon gave Mariah Carey a diamond bracelet for her birthday.
The 'America's Got Talent' presenter surprised his wife with an expensive-looking cuff decorated with sparkling butterflies to celebrate her 44th birthday yesterday (27.03.14)
She took to Twitter to write: "Nick surprised me for 3/27 with a stellar diamond bracelet encrusted with 3 floating butterflies!"
The singer and her doting husband are seen grinning ear-to-ear as she shows off her new jewellery in the accompanying photo.
Mariah was clearly delighted with the special gift and was thrilled to be having "family time" with Nick and their two-year-old twins Moroccan and Monroe together.
She added: "I'm just happy he's here!!!! #familytime #festivity @NickCannon."
The 'Honey' singer marked the occasion at the 10th anniversary of the opening of the Seminole Hard Rock Hotel & Casino in Tampa, Florida, where she tucked into a giant cake and Disney-themed sweet treats.
Butterflies have a special symbolic meaning to Mariah, whose sixth studio album was named after her personal ballad 'Butterfly', which is about the end of her marriage to her reportedly controlling ex-husband, Tommy Mottola.

Solange Knowles feels "far older" than 27.
The singer thinks marrying Daniel Smith - the father of her nine-year-old son Julez - when she was just 17 and separating less than four years later gave her an "insane amount" of perspective and says her experiences have made her wiser.
She said: "In a lot of ways, emotionally and mentally, I feel far older than 27. Just going through a marriage and a divorce - which I essentially did by 21 - will give you an insane amount of perspective on life."
Despite their split, Solange still gets on well with her ex-husband.
She told America's Harper's Bazaar magazine: "We co-parent really well. I'm able to say, 'I need to finish this album, can you step up and take care of the boy?' "
The 'Losing You' singer released her first album when she was 16 years old, and despite her older sister Beyonce being a successful member of Destiny's Child, she insists her family were never keen on her following in her sibling's footsteps.
She said: "My parents constantly tried to talk me out of being an artist. They had gone through the whole journey with my sister and just wanted me to have a normal teenage life."
And Solange - who is in a relationship with video director Alan Ferguson - admits she doesn't want her son to be a performer.
She said: "It's certainly not what I have in mind for him, I'm constantly trying to push him to work at the U.N., or be a diplomat. I try to convince him by explaining that he wouldn't have to wait in lines at the airport, and that he can park anywhere."

Amanda Bynes is "doing extremely well".
he 27-year-old actress - who completed psychiatric treatment for both schizophrenia and bipolar disorder in December following a series of public outbursts - is working hard and enjoying her classes at the Fashion Institute of Design & Merchandising (FIDM)
Her mother Lynn - who is temporary conservator of Amanda's personal and professional affairs - told People: "She is doing extremely well. She's making new friends and learning about the fashion industry."
Last week, Amanda and her parents attended a runway show at the Californian college, which showcased the work of senior students, and insiders says she fits in well at FIDM.
One source said:"She acts like any other student - focused and friendly."
The 'She's the Man' star enjoys classes so much, it was recently claimed she is planning on enrolling for more studies in April.
A source said: "If she was offered an acting job anytime soon, she may not take it because she's so focused on school."
The 'Sydney White' actress hasn't spoken much since leaving treatment, but returned to twitter at the beginning of this month to update her followers.
She wrote: "Hi everyone! I'm busy studying at @FIDM but I want to say I love you to my fans!"
She also shared a self-portrait she had drawn, and the insider said that was just a hint of the talent she is showing.
The source said: "Amanda's really talented at what she does so the picture is the real deal. She's only just beginning."
The actress originally intended to study fashion design but decided to pursue merchandise product development instead.

John Martin believes working with Swedish House Mafia has changed his life forever.
The 33-year-old singer, known for his vocals on the trio's hits 'Don't You Worry Child' and 'Save the World', admits collaborating with the now defunct group gave his career an enormous boost.
Speaking exclusively to BANG Showbiz, he said: "Working with them has changed everything, I'm just really thankful for everything that happened with the collaboration with Swedish House Mafia and them producing the songs.
"It has just made my life so much more interesting than it was before."
The success of their collaborations came as a surprise to John and even though he predicted 'Don't You Worry Child' would be a massive hit, he couldn't believe the extent of its success following its release at the end of 2012.
He explained: "I wasn't expecting to be that big, to me 'Don't You Worry Child' was a hit because I love that song and I had a good feeling every time I was listening to it ... but I could never expect that song to become that big and to see five million copies all over the world."
John will also never forget the memories he made with the band - consisting of Sebastian Ingrosso, Axwell and Steve Angello - while touring with them on what turned out to be their final run of shows.
He said: "Touring with them a year ago, when we did the last shows in Miami, that is probably what I will remember for the rest of my life because everyone was there and it was the last shows that they did so people were very emotional and there was a great celebration going on."
John's new single 'Anywhere For You' is set for release on March 30.

Bush have been recording their new album at Dave Grohl's studio.
The band, fronted by Gavin Rossdale, are busy working on tracks for an upcoming LP and have been using the Foo Fighters singer's Studio 606 in Northridge, California, to get their parts down.
The rockers are collaborating with producer Nick Raskulinecz - who is best known for producing songs for the Foo Fighters and Alice In Chains - and other than letting Bush use his studio, Grohl is not involved in the project.
In a post on his personal Twitter account, Rossdale - who also uploaded a photo of him playing guitar in the studio - revealed: "The news is out!!! we're in the thick of it with nick r, 5 more songs to sing. getting closer to the finish line. so happy to share!! (sic)"
The 48-year-old musician - who is married to Gwen Stefani - also hinted Bush will hit the road to tour the album.
He tweeted: "I think we'll tour with the record but what do i know? (sic)"
The as-yet untitled album will be Bush's first release since 'The Sea of Memories' which came out in 2011.
At the time that album had been the band's first studio album for 10 years with previous LP 'Golden State' coming out in 2001.
