Kourtney Kardashian is expecting a baby girl.
The 'Keeping Up with the Kardashians' star and her partner Scott Disick - who already have son Mason, four, and daughter Penelope, two, together - recently found out the gender of their unborn third child and the brunette beauty is said to be "thrilled" by the news.
A source told In Touch Weekly magazine:"They just found out.
"Kourtney is so thrilled; she had wanted a girl from the very start."
According to the insider, Kourtney - who has two sisters, two half-sisters, a brother and four step-brothers - had hoped for a girl because she wanted a sister for Penelope after growing up in such a female-dominated household herself.
On a recent episode of 'Keeping Up with the Kardashians', 31-year-old Scott accused Kourtney, 35, of "suckering" him into having another child.
He ranted: "This is ridiculous. It is always so sneaky with you. You need to stop lying to me. You just keep suckering me into these kids.
"I just kind of thought that at two we did not want to have any more kids and now I have to look after three. Just saying it is freaking me out."

Miley Cyrus could face a jail sentence after being spanked on stage with a Mexican flag.
The 21-year-old star - known for her controversial on-stage antics - has caused controversy after one of her dancers jokingly smacked the prosthetic butt she was sporting with the symbolic piece of fabric during her show in Monterrey, Mexico on Tuesday night (16.09.14).
According to gossip website TMZ, Miley could be in trouble because of the incident as the congress of the state of Nuevo Leon allegedly wants to take action against the pop star.
Should they be successful then the 'Wrecking Ball' hitmaker could face 36 hours in jail or a fine of $1,200.
It's not the first time Miley has come under fire for her on-stage antics. She was slammed for her performance with Robin Thicke at the 2013 MTV Video Music Awards when she stripped down to a flesh-coloured latex bikini, twerked up against his body and touched his crouch with a foam finger.
Should Miley get into trouble for her latest antics then she wouldn't be the only star to face the wrath of the Mexican authorities.
In 2008, Paulina Rubio was fined $4,000 after she appeared naked while draped in a Mexican flag in the Spanish edition of Cosmopolitan.
Her mother, Susana Dosamantes, shot to her Mexican daughter's defence insisting she didn't authorise the publication to publish the pictures.
She said at the time: "I'm not sure if the photo has been doctored, but I do know that there's a studio that took [some photos] of Paulina seven years ago that she didn't authorise to be published.
"If you look at the picture, you'll realise that it's not current, or real."

Jennifer Lawrence "couldn't take her eyes off" Chris Martin as she watched him perform with Coldplay on Wednesday night (17.09.14).
The 'Hunger Games' actress - who has been dating the 37-year-old singer since June - was spotted singing along to all of the band's lyrics as they performed at the Ace Hotel Theatre in Los Angeles and had her eyes firmly fixed on the frontman.
A source told E!: "She danced the entire time.
"She knew every word to every song and there was a glisten in her eye as she watched Chris perform.
"She couldn't take her eyes off him."
The 24-year-old beauty was said to have shared a moment with Chris - who split from Gwyneth Paltrow in March after 10 years of marriage - when he sang the group's recent hit 'Magic'.
The source added: "Jennifer stared adoringly at Chris, both hands in the hair, dancing and singing along to 'Magic'."
Following the gig, Jennifer and her pals were said to have been taken out of the venue through a private exit.
She wasn't the only star in the audience for the performance as One Direction singer Harry Styles was sat just behind the Hollywood actress.
While he is dating Jennifer, Chris is also spending a lot of time with Gwyneth, 41, for the sake of their children, daughter Apple, 10, and eight-year-old son Moses.
The former couple had brunch at the Hungry Cat in Santa Monica, California on Saturday (09.13.14).

Matthew McConaughey will not appear in 'Magic Mike XXL'.
While Channing Tatum, Matt Bomer and Joe Manganiello are all reprising their 'Magic Mike' roles in the stripper sequel, the Oscar-winning hunk - who played greedy Xquisite owner Dallas - won't be in the new movie, director Gregory Jacobs has confirmed.
According to the filmmaker, the new movie is very different to the 2012 original and will see the stripping stars go out on the road.
He told The Playlist: "It's a road trip movie and put it this way, it's different enough that once you see it you'll understand why we made a sequel. No one will be accusing us of making the same movie twice."
It was previously suggested that McConaughey wouldn't be in the sequel because his fees have soared following his award-winning role in 'Dallas Buyers Club'.
'Magic Mike' star Gabriel Iglesias, who will return as Tobias in the new film, said: "Word has it that Matt's probably not gonna be involved, because he's worth a lot of money now - that whole Oscar thing."
New faces are set to be added to the cast, though announcements have not yet been made.
'Magic Mike XXL' is scheduled for release in summer 2015.

Ben Affleck's smile landed him his role in 'Gone Girl'.
The 42-year-old actor stars as Nick Dunne in David Fincher's adaptation of Gillian Flynn's novel and the filmmaker felt the key to finding the right person for the role was getting someone who could successfully play a scene where the writer's sad expression is also perceived as the sinister grin of a man who could murder their wife.
He said: "You cast movies based on critical scenes. In 'Gone Girl' there's a smile the guy has to give when the local press asks him to stand next to a poster of his missing wife.
"I flipped through Google Images and found about 50 shots of Affleck giving that kind of smile in public situations.
"You look at them and know he's trying to make people comfortable in the moment, but by doing that he's making himself vulnerable to people having other perceptions about him."
Fincher has worked with Brad Pitt on several movies, including 'Fight Club', 'Se7en' and 'The Curious Case of Benjamin Button' and admitted he always offers every leading role on his projects to the 'World War Z' star before anyone else.
He added to Playboy magazine: "It's not because I'm pathetic but because he's good for so many things."

Holly Willoughby has bid a tearful farewell to 'This Morning'.
The 33-year-old beauty - who is expecting her third child with TV producer husband Daniel Baldwin - filmed her last episode of the ITV series before going on maternity leave this morning (18.09.14) and struggled to fight back her tears.
Speaking as her replacement Amanda Holden walked on set to present her with a bouquet of flowers, Holly said: "I'm officially handing my baton over to you, look after my Phillip [Schofield]."
The former 'Dancing on Ice' presenter - who is also taking a break from her duties as a team captain on 'Celebrity Juice' - then received a phone call from her husband, causing her to burst into tears as she said goodbye to the 'This Morning' team.
Dan said: "We can't wait for you to come home, all of us. The kids are so excited. We were talking about it this morning. I think [our daughter] Belle thinks you got the sack!"
Holly's husband - with whom she also has son Harry - then joked that they were expecting a second daughter, which she quickly denied.
He said: "I just wanted to say, have you made the announcement yet that we're having a baby girl?"
Holly added: "No we're not, we really don't know."

Julian Fellowes admits it was a "great privilege" to have George Clooney star in a 'Downton Abbey' special.
The creator of the ITV period drama heaped praise on the Hollywood actor for filming a cameo in an upcoming mini-episode of the programme for ITV's Text Santa charity, insisting it was "very sweet" of him to agree to be in the Christmas show.
Speaking at a CTBF (Cinema and Television Benevolent Fund) charity screening of 'Downton' in London's Leicester Square last night (17.09.14), he told BANG Showbiz: "He very, very, very kindly agreed to come and be part of a little special we did that supports the ITV group of charities.
"It was a great privilege and pleasure to have him on the set, and he was very sweet to do it."
Julian, 65, joked that George probably only came on board because he knows 'Downton' star Hugh Bonneville - who plays the Earl of Grantham in the programme - but admitted the 53-year-old hunk was very complimentary about the series.
He added: "He and Hugh have just made 'Monuments Men' but he did seem to like the show, but he would say that wouldn't he?
"We all worked on it [the special episode] and it was marvellous."
And fans of Dame Maggie Smith, who plays the Dowager Countess of Grantham, will be pleased to hear Julian insist there is "no chance" of her alter-ego being killed off in the period drama.

Stephen Fry has hinted he may have recorded a cameo for 'American Dad!'
The 'Blackadder' star has a number of voice acting roles under his belt and he's now revealed he may have added another to his CV by taking on a role in the US animation series.
Writing on Twitter, he said: "That was fun - just played an @AmericanDadFOX character. My life is complete."
The 57-year-old actor and comedian - who has starred in a number of blockbuster movies including 'The Hobbit: The Desolation of Smaug' and 'Sherlock Holmes: A Game of Shadows' in addition to his TV roles - went on to joke that he wouldn't be happy until he'd appeared on long-running BBC medical drama 'Casualty'.
He added: "Oh wait, I haven't been on @BBCCasualty yet. (sic)"
Other stars who have had cameos in 'American Dad!' - which was created by 'Family Guy' funnyman Seth MacFarlane - include Amanda Seyfried, 'Mad Men' star Jon Hamm and Mariah Carey, although it is so far unclear whether Stephen himself is set to appear in an episode.

Cher is being sued for allegedly complaining she had too many black dancers.
Choreographer Kevin Wilson has filed legal documents against the 'Believe' hitmaker for racial discrimination and retaliation, and in his claim he states the 68-year-old singer told him to find a white, blonde dancer while auditioning for hopefuls for her 2014 'Dressed to Kill' tour after he said he liked a "minority female dancer".
According to Kevin, Cher said: "We have too much colour onstage" and instructed him "not to cast anymore dark skinned black dancers on the tour."
According to the lawsuit documents obtained by TMZ, a male dancer invited a female fan to his hotel room after a show in June and got "sexually aggressive" with her, an incident Kevin claims Cher tried to cover up.
The choreographer alleges he and two other whistle-blowers were fired, while the dancer was kept in the show, but they were told they were being dismissed due to "budget cuts", despite the tour grossing a reported $54.9 million.
A spokesperson for the singer branded the allegations "ridiculous" and any suggestions Cher said anything racist is "absurd".
They said: "These are ridiculous allegations. They couldn't be further from the truth."
Her lawyer said of her alleged racist statements: "[These are] untrue and categorically denied. To attribute such a statement to Cher is absurd."

Joan Rivers left a big part of her $150 million fortune to her dogs.
The 81-year-old comic - who died earlier this month after suffering a cardiac arrest while undergoing throat surgery - wanted her four rescue animals to continue to lead lives of luxury when she passed away and so her will asked for her assets to be given to her daughter Melissa, grandson Cooper and her beloved pets.
A source told the New York Daily News newspaper's Confidenti@l column: "Those dogs are her family. They meant the world to her and Joan wanted to make sure that if anything happened to her that they would be taken care of."
However, the pampered pooches will no longer live in her $35 million New York apartment but will move in with Joan's longtime assistant Jocelyn Pickett.
Melissa is planning to sell her mother's penthouse apartment, as well as another in the same block which Joan bought for her daughter and grandson to live in while in the city, because she finds it too "painful" being in New York.
The source said: "Melissa is based in L.A. and has no need for a place in New York any more. It's also too painful; Joan loved the city so much.
"Melissa is a West Coast girl and Cooper is in school in L.A., while her mom was East Coast-based. Additionally, Melissa is planning to sell Joan's amazing home in Connecticut."
Meanwhile, it has been revealed Joan had been working on a new show, 'Ask Joan', with Andy Cohen and his Most Talkative production company before she died.
A source said: "Joan loved Andy, she loved his talent. "She thought he was a producing genius and was excited that he was going to produce a new show where Joan would answer questions. Andy has a deep relationship with NBC, which is now run by Ted Harbert, who loved Joan. It was all positive stuff happening."

Iggy Azalea has had a "hell of a week" but her fans' love has pulled her through.
The 'Fancy' hitmaker's ex-boyfriend and former manager Hefe Wine is said to be in possession of a sex tape featuring the pair from when they dated and he has been offered a seven-figure sum to sell the footage to porn manufacturer Vivid Entertainment.
Iggy - who has denied the tape even exists - made reference to the problem during her sell-out concert at the O2 Shepherd's Bush Empire in London on Wednesday night (17.09.14), telling the crowd: "I've had a hell of a week."
But the 24-year-old rapper insisted the love and energy she was feeling from her British fans was making the drama in her life melt away.
She added: "Sometimes I think you can have the most awful, terrible week, but, for me, coming here and seeing your faces makes me realise I still have the best life."
Iggy treated her loyal followers with a set packed with hits, including
'Change Your Life', 'Work' and a sexually charged performance of 'Bounce', during which she was joined by four leotard-clad dancers.
She also spat rhymes from 'Problem' - her duet with Ariana Grande - and 'Fancy', her collaboration with Charli XCX.
The highlight of the show was when Iggy was joined on stage by Rita Ora for a rendition of their new single 'Black Widow'.
Iggy bizarrely hid under a white blanket with a grimacing face drawn on it and her name written on it.
