Justin Bieber wants Selena Gomez to be the mother of his children.
The 20-year-old singer reportedly wants to start a family with the 22-year-old brunette whom he has been dating on and off for four years, and wouldn't be upset if she got pregnant soon.
A source said: "They have a very romaticised and immature idea of what it means to have a child. When they first fell in love, they promised each other that they'd be parents one day, and Justin still says he wants Selena to be the mother of his children, especially when he wants to make her happy.
"They're rolling the dice, because they think whatever happens is God's will."
But friends close to the couple think their turbulent romance is toxic.
Another source told US OK! magazine: "They're so irresponsible when they're together. Every time they start seeing each other, they make all kinds of declarations of love and talk like they're going to be together forever.
"But their relationship is dangerously toxic, and they're the only ones who don't realise that."

Gwen Stefani spends $1,000 a week on her nails.
The 'Voice' USA mentor is reportedly addicted to manicures and pays a professional beautician to visit her Beverly Hills mansion to ensure her nail polish is immaculate and matches her outfits at all times.
A source told Star magazine: "Gwen spends $1,000 a week on her manicures. She pays $300 for her manicurist from Nails by Design to come to her Beverly Hills home, and the other weeks she did that three times. The amount she spends on her nails is unreal."
The blonde beauty, who has three sons, Kingston, seven, Zuma, five, and Apollo, six months, with rocker husband Gavin Rossdale, previously admitted she hates when her nails aren't perfect.
She said: "When my nails are done, I feel more complete, more ready."
The No Doubt frontwoman, 44, also once confessed she is extremely vain, joking that could be her "middle name".
During an interview in 2011, she said: "I mean, I'm very vain. That would be my middle name. Of course I am, you know what I mean? I love the visual."

Lydia Bright thinks she and James 'Arg' Argent would be living together in Spain if they hadn't joined 'The Only Way Is Essex'.
The couple have enjoyed an on-again off-again relationship since joining the ITV2 reality series and although Lydia doesn't blame their break-ups on the show, she admits their lives could've been very different if they'd never joined.
Quizzed on what she'd be doing now if she'd never been on TOWIE, she told Now magazine: "I actually don't know ... I took a gap year and was working in admin in Camden. I hated it - I found it really boring.
"Then my auntie said James and I should go and work in her bar in Spain, so we moved there and shortly after that, TOWIE came up. So who knows what would've happened?
"Maybe I would've gone to uni [university] or perhaps me and James would still be living in Spain."
The blonde beauty reunited with her former flame when she returned to the reality show in the latest series, and although they're not officially back together, Lydia, 23, thinks there will always be something between them.
She said: "Me and James have a long history - we were together for three years before the show and a year when we were on it.
"We're just two normal people from Essex who've been on this massive rollercoaster. Our lives have completely changed."

Are Beyoncé and Jay Z expecting a baby?
Rumours have sparked that the couple are expecting their second child after Jay Z changed some of his song lyrics.
Numerous news outlets are reporting that Jay Z hinted that his wife was pregnant during 'Beach Is Better' whilst the couple performed their 'On The Run' tour in Paris.
The 32-year-old rapper reportedly changed the lyrics to say: "Cause she's pregnant with another one."
The pair - who married in 2008 - already have two-year-old Blue Ivy together.
Rumours that Beyoncé is pregnant have been circulating for the last few weeks.
A source recently told the US OK! magazine: "For the last month, Jay has been fiercely protective of her, just like he was when she was expecting Blue Ivy.
"He's been doing everything he can to ensure that Bey is in a stress-free bubble. He's informed their entire entourage that they need to use relaxed voices, mellow lighting and listen to only soft music, and he's said that all of the food Beyoncé eats should be organic."
The source added: "He's really doing his best to make sure that she's as comfortable and healthy as possible."

Andrew Garfield thinks the hackers who leaked nude photos of celebrities are "misogynistic" and "revolting".
The 31-year-old 'Amazing Spiderman' star is the latest person to defend his fellow celebrities after the naked photos of female stars like Jennifer Lawrence and Kate Upton were stolen and posted online.
He told The Daily Beast: "It's disgusting. 'I have a right to your naked body or images that you've sent to your husband, or lover'. It's disgusting.
"It's violent, and it's misogynistic, and it's revolting, and it's another example of what this distance has enabled us to do - it's enabled us to be disassociated from each other.
"There's enough awful s**t coming from it that hopefully we'll get to the point of, 'OK, wait a second.' What's scary is that we haven't reached that point yet, and there hasn't been a referendum put on it."
Meanwhile, it was revealed that some of the stolen nude celebrity photos will be displayed in an exhibit at a US gallery.
The artist, known as "XVALA", will use the images as part of her "No Delete" show in the Cory Allen art gallery in St. Petersburg, Florida.
Speaking about the artist's decision, Andrew said: "The Internet is the new Wild West. There's a guy now taking these pictures and putting them up in an art gallery.
"What f***ing right does he have to do that? It's absolutely revolting."

Lamar Odom is desperate to reconcile with Khloé Kardashian.
The 'Keeping Up With The Kardashian' star's ex-husband is reportedly ready to fight for Khloé after she split with her boyfriend of eight months, French Montana.
A source told Hollywood Life: "[The split] makes it that much easier for him to get back with her and be her husband.
"He wasn't too fond of that rapper anyway and thought he was a sucker - Khloé's rebound man!"
The 30-year-old television personality split from the basketball player in December last year after four years of marriage.
The source continued: "Real love always wins in the end. He knew that wasn't going to last.
"French was there so she could get her mind off Lamar. We all know that. He did his job, played the role he was supposed to play, and now he's gone. Just like that!"
However, Khloé's mother, Kris Jenner, is reportedly worried that the couple will now reconcile their differences.
A friend of the family said: "Kris thinks Khloé is very vulnerable right now and the last thing she needs to do is jump back into a relationship with Lamar.
"Kris always feared this would happen because she knew, as Khloé's mother, that her daughter wasn't over Lamar. Call it a mother's instinct."

Sky Ferreira is "obsessed" with Taylor Swift.
The 22-year-old singer tweeted the 'Shake It Off' hitmaker to admit her adoration.
She tweeted: "I'm obsessed with @taylorswift13. I'm so late?!??!?!" (sic).
The 'Boys' hitmaker was thrilled when she was tweeted back by her new-found idol.
Taylor replied, writing: "I love your record! 'Boys' is on every playlist of mine."
After retweeting Taylor, Sky couldn't help but show her excitement by writing: "That RT was so not humble".
Meanwhile, Taylor has revealed she's looking for "smart, exciting people" to become her friends.
She said: "I choose my friends based on people I have things in common with or people who challenge me. I think that it doesn't matter what career my friends have.
"It's just based on the fact that I can really relate to people who are driven and intelligent. I think that there's something inspiring about being around people who know what they want, people who are passionate about something.
"You want to be around, like, smart, exciting people. I think that's what brings you up."

Lindsay Lohan blames her Oprah show for forcing her out of the United States.
The 28-year-old actress made a 'docu-series' last year, showing her battle to get things back on track, which was aired on the Oprah Winfrey Network.
She explained to the Telegraph: "After the Oprah show it was kind of hard for me to be in New York.
"There started to be paparazzi, and I didn't have that in New York in the beginning...Every time I left my house, they were at the corner."
The 'Mean Girls' star also complained about the judge's decision to sentence her to community service at a morgue after she disobeyed her probation in 2011.
Lindsay said: "It was "f***ed up and inappropriate.
"Because a lot of other people were meant to do it, and they were like: 'No, they can't handle it. Lohan can.'"
However, Lindsay's move to the UK - where she is starring in 'Speed-the-Plow' in London's West End - isn't all bad for the actress as she recently revealed she thinks English guys are cute.
She said: "Being here in London is all about me this time. Yeah English guys are cute, but it's not about the boys.
"It's about getting away from New York and Los Angeles and starting afresh, which is all very exciting for me.
"I love London and lived here for eight months once before, so it feels like home."

Tom Hardy hates being followed.
The 36-year-old actor insists that being an actor shouldn't have to mean being famous.
He told USA today: "I hate being tracked or followed. I don't like it when people say, 'Well, you should have expected that when you accepted the job as an actor'.
"When you go to drama school, no one gives you a class on fame ... Just treat people how you wish to be treated."
Tom - who is rumoured to have married actress Charlotte Riley - has also revealed that if any rumours were to be confirmed, it wouldn't be through him.
He said: "Whether I'm married or not married, people will find out. But it's also not something I'm going to offer."
Meanwhile, the 'This Means War' star - who is known for his roles in more serious films - has admitted he won't make a permanent switch to starring in romantic comedies.
When asked about filming for the 2012 film starring Reese Witherspoon, he said: "I didn't understand how you could do something which is so much fun and be so miserable doing it.
"I probably won't do a romantic comedy again."

Martha Stewart thinks Gwyneth Paltrow should stick to acting.
The 72-year-old lifestyle guru has blasted the 41-year-old actress and her lifestyle website, Goop.
Talking to Net-a-Porter's Porter magazine, Martha said: "[Gwyneth] just needs to be quiet. She's a movie star.
"If she were confident in her acting, she wouldn't be trying to be Martha Stewart."
It is not the first actress-turned-lifestyle guru that Martha has blasted.
Recently, when speaking about Blake Lively's lifestyle blog and brand, Preserve, Martha said: "Let her try. I don't mean that facetiously! I mean, it's stupid, she could be an actress!
"Why would you want to be me if you could be an actress? I just did a movie yesterday, though - I can't even tell you about it - but I want to be Blake Lively."
Despite the verbal bashing from her pal Martha, the 'Gossip Girl' star was happy to stand up for the television personality and 'Iron Man' actress, explaining that their work allowed other women to get involved in lifestyle websites and blogs.
She said: "I'm always the first person to defend Gwyneth Paltrow.
"Or any woman in a position of power, like Martha Stewart or Oprah, who gets burned because they have paved the path for so many other women who are doing something they believe in."

Kendall Jenner doesn't want Kim Kardashian at her fashion shows.
The 18-year-old television personality and model is keen that the 'Keeping Up With The Kardashians' star stays well away from any of her modelling gigs.
She told The Cut magazine that Kim was regularly invited to the shows but she would always check with her half-sister before making an appearance.
Kendall explained: "She called me before and was like, 'Hey I was invited to the show, I just wanted to let you know. Do you want me to come?' and I was like, 'No.'"
Meanwhile, the model has revealed she must "work harder" if she wants to be taken seriously by the fashion world.
She said: "I want to be high fashion. I want to be taken seriously.
"People think that this [success] just came to me. But it didn't. What I have has almost worked against me."
Kendall also explained that her reality television roots had made it difficult for her during castings.
She added: "People didn't take me seriously as a model...I went on castings and some people weren't feeling me because of my name. But it was great when people didn't recognise me. I was like, 'Thank you. Please don't recognise me.'"

Chris Martin has introduced Jennifer Lawrence to his friends.
The 37-year-old Coldplay frontman reportedly invited 'The Hunger Games' actress' to a dinner at Chateau Marmont in West Hollywood with his pals.
A source told E! News: "They seem very comfortable in each other's company - and happy!
"It doesn't seem like it's a new relationship. They seem super affectionate and at ease with each other."

The source added: "She is very gregarious and confident ... They seem super cute together."

The insider said: "He writes her songs and loves taking her to private romantic spots. Chris is sweeping Jen off her feet. That's his thing."
