Rob Kardashian is reportedly moving in with his sister Khloe.
The 27-year-old star has been in a "dark place" since learning that he is at risk of developing diabetes and eventual organ failure due to his recent weight gain.
However, he's planning on living with Khloe, 29, who has just bought Justin Bieber's former house in Calabasas, California, because he wants her to help him shift the extra pounds and make sure he keeps it off.
A source told Us Magazine: "Living alone isolated him. Rob needs to be around people who love him."
Rob will also have his sister Kourtney close by as well as she has just bought a property in the same gated community, The Oaks.
The sock designer previously lived with Khloe and her ex-husband Lamar Odom at their former marital home in Tarzana, California, but he moved out last year after he failed to stick to his weight loss plan.
Meanwhile, Rob - whose father Robert Kardashian died aged just 59 from oesophageal cancer in 2003 - is reportedly refusing to attend his sister Kim and her fiancé Kanye West's wedding next month in Paris, France, because he's embarrassed of his weight gain.
A source said previously: "Rob is upset about his changing shape and truly feels like the black sheep of the family."

Katy Perry is reportedly "doing really good" following her split from John Mayer earlier this year.
The 'Dark Horse' hitmaker was devastated when her two-year romance with the singer ended in February, amid claims he had cheated on her, but she's currently focusing on her upcoming 'Prismatic' world tour, which kicks off next month, in a bid to get over her recent heartache.
A source told E! news: "She is in great spirits right now.
"Katy is focused on her tour right now. She is not allowing anything to distract her from it."
The 29-year-old singer - who was previously married to Russell Brand - has split with the 'Gravity' star twice before, but this time she is determined the relationship is over for good and has been using hypnotherapy to help move on.
A source said previously: "Katy has been really hurt by John and she doesn't want him worming his way back in.
"He hates women moving on from him but this time she's determined to erase him from her life. Her first step was to get him to move all of his belongings out of her home.
"Katy wants a fresh start and she is well on her way to putting her relationship with John firmly in the past."

Emilia Clarke wants as many as children as she can "pop out"
The 'Game of Thrones' star, who plays the mother of dragons on the HBO series, would like to have a massive brood because she wants to create a "happy family".
Speaking in the May issue of Marie Claire magazine, she said: "Personally, I'd like as many children as I can pop out, I reckon. You come from a happy family; you want to create a happy family."
The 26-year-old actress - who previously dated 'Family Guy' creator Seth MacFarlane and was caught flirting with Jared Leto at the Screen Actor's Guild (SAG) Awards in Los Angeles in January - was recently voted the world's most desirable woman in a new international poll by online men's magazine AskMen.com.
The brunette beauty was awarded the title after winning over the majority of one million voters, who were asked to select stars based on sex appeal, shared values, talent, overall desirability, and potential in the upcoming year.
Explaining the results at the time, the website said: "Emilia Clarke may be known mostly for her role as Daenerys Targaryen, but to viewers the other worldly beauty is everything. This will be her year."

Andrew Garfield stole a Spiderman costume from the set of his new movie 'The Amazing Spider-Man 2'.
The 30-year-old actor - who plays the comic book hero in the new movie franchise - was forbidden from taking his character's outfit for a keepsake, but he managed to smuggle the tight jumpsuit by hiding it in his suitcase.
When asked if movie bosses allow him to keep the infamous outfits after filming, he told Scott Mills on Radio 1 today (09.04.14): "You know what, they don't, but I may have stolen one and it may be in my luggage, it may be in my hotel room luggage. It may even be in my back pack in the car. It's possible."
However, Andrew is adamant no one will miss the costume because there are loads on set.
He explained: "There are a lot, there are about 23, 24, 25. I don't know, there are a lot of them because they are all in different states of duress and distress. But yeah, they are very snug."
The 'Social Network' star believes shooting his scenes on set is similar to dressing up on Halloween for the spooky yearly holiday occasion.
He said: "Its pretty similar to [dressing up on Halloween] to be honest. That's how I feel when I'm making these movies. I feel like I'm just on an extended Halloween. In a brilliant way, you're kind of naked."
Although his girlfriend Emma Stone, 25 - who was appearing on the breakfast show with Andrew - admitted seeing her beau in the revealing outfit took some getting used to because she kept getting "distracted" by his muscular figure bulging out of the skin-tight suit.
She said: "The first time I saw it I was incredibly distracted but you get used to seeing a man in spandex all day."

Peaches Geldof's Instagram account has been shut down.
The 25-year-old TV personality regularly updated her fans with cute snapshots of her family on the photo-sharing site, but her profile has now been disabled, at the request of her family, following her tragic death earlier this week.
A spokesman for Instagram told the Metro newspaper: "When a person passes away, we do honour requests from close family members to deactivate their Instagram account, which removes the profile and associated information from the site."
Peaches - who has two sons Astala, 23 months, and Phaedra, 11 months, with her husband Thomas Cohen - was found dead at her home address in Kent, South East England on Monday (07.04.14), and a post-mortem conducted today (09.04.14) proved to be "inconclusive."
The family of Peaches, the daughter of Bob Geldof and the late Paula Yates, will now have to wait for a toxicology report - including test results for drink and drugs - which could take up to several weeks.
Police have so far described her death as "sudden and unexplained", but non-suspicious as there were no drugs or suicide note found at the house.
Kent County Council said previously: "A decision on whether there needs to be an inquest depends upon the final results of the post-mortem."

Amanda Bynes doesn't have schizophrenia.
The troubled actress, who completed psychiatric treatment in December following a series of public outbursts, has asked her lawyer, Tamar Arminak, to shoot down rumours claiming she suffers from the mental disorder.
Speaking to People magazine, Mr Arminak said: "There has been much speculation about Amanda's medical condition. She has remained silent because she believed it was best to keep her mental health diagnosis private.
"However, she asked me to dispel certain rumours. For the record, Amanda does not have schizophrenia, nor has she ever been diagnosed with it."
The attorney also claims the 28-year-old star, who chucked a marijuana bong out the window of her apartment in New York City last May, has never abused drugs or alcohol and she quit cannabis nine months ago.
He explained: "She's devoted to living her life as healthy as possible. She's never had a history of abusing alcohol or hard drugs, and she's proud to say she's been marijuana-free for the past nine months."
The 'Sydney White' actress, who was arrested last July after setting a small fire outside an elderly woman's home in Los Angeles, is now hoping to rebuild her life and has become a student at the Fashion Institute of Design & Merchandising (FIDM).
A source said previously: "She's a great student who always participated and really cared about her classes. She really fit in and loves her school."

Stacy Keibler is expecting a baby girl.
The 34-year-old star and her businessman husband Jared Pobre, who got married last month in Mexico, will welcome their first daughter into the world this summer.
A source confirmed the announcement to E! news, before adding that the brunette beauty and her spouse can't wait to meet the tiny tot in a few months.
The insider said: "They're beyond excited and happy."
Stacy - who previously dated George Clooney - announced she was expecting her first child last month, just two weeks after tying the knot, and was "elated" to be starting a family.
She said previously: "More blessings!! We're an elated family-to-be!"
Jared, 39, added: "I'm extremely excited about starting a family and building a future with Stacy."
The pair shocked everyone last month when they got hitched in a romantic beach setting, with just their immediate families present to witness the nuptials.
However, Stacy admitted her wedding was better than she even "dreamed" it would be.
She said at the time: "It was such a celebration of love with the whole family, better than I could have ever dreamed of. We can't stop smiling."
The couple have only been dating since late last year, but have known one another for five years.

Alesha Dixon won't jump ship from 'Britain's Got Talent' to 'The X Factor'.
The 35-year-old singer, who shot to fame in girl band Mis-Teeq, has recently been rumoured to join the singing competition's judging panel with 'BGT' co-star Simon Cowell and pal Cheryl Cole, but she insists she is not swapping sides, although she finds the idea "flattering".
Meanwhile, Simon, 54, hasn't ruled out hiring the songstress for 'The X Factor' panel, however, he doesn't think Alesha would be interested as she is loyal to 'Britain's Got Talent'.
Speaking at the launch of the new series of 'BGT' in London today (09.04.14), he told BANG Showbiz: "Alesha would be great on the show, but whether she wants to do it, I don't know. She loves 'Britain's Got Talent.' "
Simon also admitted he is no closer to finalising the line-up - which is also rumoured to include veteran judge Louis Walsh - as he is determined to find a judge who is hands on.
He explained: "It's such a big job to do. What I'm trying to get my head around is, I want someone who's gonna actually be a great mentor, not just someone who's famous. And someone who's going to put the hours in - that's what is so important. I've got to find someone whose schedule from October to December is free. It's hard.
"We'll hopefully see what we can do this year. I've got Cheryl by my side, I'm back on form, and we're going to find a star."
'Britain's Got Talent' begins Saturday (12.04.14) at 7.15pm on ITV.

Simon Cowell is set to hold crisis talks with James Arthur.
The 54-year-old music mogul has denied dropping the controversial 'X Factor' winner from his record label, but admits the troublesome star - who was reportedly fired for rapping about a terrorist attack on his upcoming mixtape - needs to "calm down", and he is planning to hold a meeting with the 'Get Down' crooner soon.
Speaking at the launch of the new series of 'Britain's Got Talent' in London today (09.04.14), Simon told BANG Showbiz: "I think him and I need to sit down and have a conversation, to be honest.
"I haven't phoned him but I'm going to have to sit down with him. Apart from anything else, this silly 'You said this, I said this...', it's all nonsense. He's just got to calm down a bit."
Simon also addressed the 26-year-old singer's jibes on Twitter towards his management and publicity teams, insisting James is entitled to his opinion but ought to "relax".
He reasoned: "On one side it's annoying [as a label executive], on the other side it's like, you know what, he's entitled to say whatever he wants to say.
"What I would say to him is to put things into perspective: you won a show, you wouldn't have got a record deal - probably - without the show, you've sold a ton of records, you're famous. Just go in the studio and make a great record. Relax."

Jane Fonda says society gives teenage girls "conflicting messages".
The actress and fitness video pioneer believes young girls are bombarded with the message to stay a virgin until they're married, yet, at the same time they're encouraged to have a certain sex appeal by music videos and movies.
The 76-year-old star says: "[Adolescent girls] have so much more pressure from the media. You're supposed to be sexy, you're supposed to be thin ... and yet family values and societal values kind of say, 'Be a good girl, and a virgin until you're married.' Conflicting messages are coming at them."
Jane insists men face the same pressures and are taught to embody the masculine stereotype, which is unhealthy.
She told 'Entertainment Tonight': "The message to boys is, 'Be a man. Don't cry. Don't show emotion. Don't love your mother too much.' All those kinds of things. And it develops a kind of toxic masculinity."
She recently recalled her difficult upbringing after her mother Frances Ford Brokaw took her own life when Jane was just 12 and she says her father, actor Henry Fonda, was distant and difficult.
She also claims her stepmother would insinuate she was overweight which resulted in her developing having self-esteem issues and developing bulimia.
She explained: "I never felt pretty or confident. My dad wouldn't tell me [I looked fat] directly; he would have his wife tell me that my bathing suit was too small or my belt was too tight or my skirt was too short. I became bulimic and anorexic, the whole thing."

Demi Moore avoided ex-husband Bruce Willis when the pair watched their daughter Rumer perform in Hollywood.
The former couple, who split in 2000 after 13 years of marriage, were at DBA in West Hollywood on Saturday (05.04.14), but decided to sit in different areas rather than socialise with each other.
A source told Us Weekly magazine: "They stayed after to congratulate her and chat for a bit. Bruce and Demi did not interact with each other."
Demi, 50, was accompanied by a male friend and two women for the night, while Bruce, 59, was joined by his pregnant wife Emma Heming-Willis.
The families watched Rumer, 25, play a number of roles in 'For the Record: Tarantino', a mash-up that pays homage to several of director Quentin Tarantino's hit movies, including 1994's Pulp Fiction, in which her dad Bruce starred in.
The source added: "Bruce was cheering Rumer on. So was Demi!"
Bruce, who also has Scout, 22, and Tallulah, 20, with Demi, will soon welcome his second child with Emma. The couple also have a 23-month-old daughter, Mabel.
Meanwhile, Demi has been dating rocker Sean Friday for nine months, after her split from ex-husband Ashton Kutcher, who is expecting his first child with fiancée Mila Kunis.
